Damn! Heh, come do mine next!

 

Thanks DenverCityCat.. I am still collecting some parts to finish my truck. When I get them all rounded up, I will get back to it. When I get done with this truck, I really want it to be the best one I have done yet and run the miles up on it.

I have seen what two guys can get done on a project when working on one and it makes it go 10 times faster then when it is just one guy working on one. I wish I could find someone in my area where we could focus on a truck for just a few days at a time and have all the parts and materials needed to work on it. It goes so quick and easy.

A little at a time and you will get it.

 

22R Main Harness PN#82131-89298

This is not my truck but what it is going to look like one day when I am completed with it on the outside and want the interior looking new on the inside.

 

Never thought I would be going to carburetor but lately my truck runs great but seems like when it gets damp it acts up and I cant figure it out or more likely really don't feel like chasing it out. Some days it runs fantastic and just seems it is more on damp days. Also I have still yet to figure out Misty's cherry manifold and I have had it to the dealer and supposedly some of the Toyota gurus in my area and they are stumped on it as well.

When EFI is working great it is great but in my opinion the sensors need to read the correct voltage and with the crimps and wiring just starting to age, I feel the sensors just don't get the correct voltage that is needed or something. For as long as I intend to keep my 85 and two of my runners I want something simple and dependable so will be doing the Weber.

I originally wanted a unique fully loaded 85 extra cab with all the lights bells and whistles but this is going to be my everyday work truck and all those add ons are just something else to have to work on. The current harness and options on my 85 will swap over to the red runner which is a fully loaded runner that is missing some of the pieces my 85 currently has on it. Being an 85 and extra cab with the SR5 options that I can add to it that don't involve the harness is fine with me.

Getting ready to swap harnesses hopefully for the last time. Swapping harnesses is not a difficult job but it does take some time. For as well as I know how it all goes in it is still about a 40 hour job. Going to carb is going to take a few small things that I will need to figure out but nothing I am worried about.


Some changes Toyota does is in plug differences. Here is the fuel tank and tail light harness changes. There is actually another style plug that Toyota uses.


I always thought that the Wiper Delay was installed in all harnesses but maybe it isn't in the carb harness. These are two different harnesses. The one with the plug is where you add the little adapter harness and the green wiper delay box. The other harness does not have this option. The jumper plug with the wire in it is where the mini adapter harness goes.


Yeah, butthead splices I get to fix. I just don't understand why people don't just get the soldering gun out and fix one correctly. I have yet to see a harness not butchered up in some way. I have spent more time taking them back to the way the Toyota made them. Most options like stereos and trailer light kits are available.


Here is the Wiper Motor harness. 4 wires on each plug. The round plug is for 86 and older and the square plug is for 87 and newer. One way to identify which year a truck is under the hood along with O2 sensors and a few other ways. Two of the blue wires are the same and two don't match up. I will just swap out wiper motors to save me having to switch plugs.

On the 86 and older wiper motor round plug, it is the exact same plug that is on the Starter Relay on the 87 and newer trucks.


If I did not have 50,000 things going on I would like to get my hands on this truck. It looks rough but is actually in great shape. The frame had a small rust hole that most would not mess with but would be easily fixable. Frame is rock solid, body is straight, and I was shocked to see how well the floor boards were in this 81. It is an SR5. If only I had more time. One day I want to fix an early first gen.

 

a solid 81 jeezz terry are ya sure you dont have some spot ya could like hang that from th rafters for the time being lol

 

Terry iF you were closer I have an 82 cab I would just give you..

I admire you tacking the harness swap, way better way to go than slicing and dicing the harness

 

Hey Terry. Glad to see you are still plugging away at your projects.
I do not like doing wiring!!!!

Are you getting the shop ready for the winter?

We have been lucky up here with the weather. So nice lately. 50's and sun!!

I've been busy at the shop and with my runner.

 

Hello Cyberhorn.. I wish I had the time to fix one. I do know where a couple of descent trucks are sitting that would make great projects if I do get the fire to get one done.

Hello Robb... I have seen 3 trucks where someone tried to make an EFI into a carb and it is horrible. I have replaced the wiring in one of them to what it should of been done to get it correctly. I have spent many hours fixing harnesses.

Hello Mark.. Weather has been descent here, not sure how much longer it is going to last. I know anytime after Halloween the temperature tends to drop quick. I don't care for winter at all but I will say that it is easier to warm a shop then it is to cool it down. Last year was really the first winter I have really enjoyed, only when I was in the shop, once I come out of the shop I don't care for it.

Funny that you mentioned getting the shop ready for winter. Misty got her an out door fireplace like thing and has been going thru my fire wood pile really fast. I brought truck load home a few days ago.

Doing wiring is not bad at all, but it is time consuming. You have to tear everything so far down to get it done correctly. I have yet to see one not chopped up somehow and spend a lot of time getting them back to factory. Never did understand why people butcher them up so bad.

 

I got my Weber in the mail today. I was hoping to have the truck ready to put the Weber on but am just now getting to it. I am going to be putting in a lot of hours at work soon as one of the guys is going to be off for a while. Hope to get the swap done before that starts up.

Here is what it looks like now.


My new Weber. Not to happy having to give up my SR5 options but I am tired of battling EFI problems. I have helped a friend convert several to carb. He finally talked me into it. Once I get mine converted over, Mistys will eventually get converted to carb since I cant figure out the cherry manifold fixed.


Spent the day trying to get things swapped around. I helped a friend in the past convert one from EFI to carb and for some reason you have to swap out the headlight/fuse box harness as the heater blower motor wont work. I know from following the electrical diagram the white wire from the alternator basically goes to the white wire in the main harness and down to the blower. One reason when you rev the motor the blower can speed up.

I did not get as far as I would of liked but I did get the main harness out and the new on in. Dash is mostly reassembled, all of the EFI stuff off, getting the carb tank ready to go in. Doesn't sound like much but it is quite a bit. I am beat and will try to see what I can get finished tomorrow.

 

I busted my rear hoping to get my truck swapped over today but I did not get it finished. Got the gas tank swapped out, got the dish that drives the mechanical pump, most of the fuel lines ran, distributor in, got the intake cleaned up, inner fenders back on, some more of the dash back in, wiper motor swapped out, and several small things that just add up and take time. Doesn't seem like much but I got after it at 4 this morning and just now stopped on it.

The carbureted trucks have the fuel filter mounted just out side the tank, a difficult place to get to it and change it out. I am relocating it to under the hood. I got to stop at Toyota in the morning to get the gasket that goes in between the fuel pump and head. I know I have one or two laying around but am unable to find one. I asked a friend of mine and he said he had one but was unable to find it. One of the odd parts that just disappears.

Converting one to carb is a bit out of my league. I know how fuel injection is set up but am weak on carbureted trucks. I am going to use my brothers 22r truck for a reference tomorrow if all goes well. I got 2 long days in getting this swap done with the correct harness instead of hacking a fuel injected harness to make it work. Every truck I have seen where they tried to convert and EFI to Carb using a EFI harness has been a hack job. I can still see a full days work on getting things finished up.

 

Sheesh, Terry! I can see why you had to leave the '81....how you have time for all that you do now I do not know.

Don't worry about that little gasket, it's just in hiding until you don't need it any more.

 

Hello Hab, Funny about things disappearing, I was working with a friend recently and a truck was on the lift. We had bolts on the lift and I bumped one. We could not find it for nothing no matter how hard we tried to find it. His wife found it in the dryer as it had fallen into one of his pockets and neither of seen it go in there. Things happen. Wish I had more time as there are plenty of cars and trucks that I would like to fix. Maybe someday. Retirement is getting closer (11 more years) hope I have the energy to get out and stay busy then.

 

A friend is helping me with the Weber conversion. So much easier then having to look things up and figure it out on my own. Been several years since I messed with carburetors that I have forgotten about them and never messed with a Weber. Keeping track of what I have done so far for future reference.

Started to clean up on of the Intakes I had and broke a bolt trying to get it out. Luckily I have 3 more so got another one to clean up and use.

A bunch of carbon in this bolt hole.


More carbon here and will eventually become the vacuum port for the PCV valve. This is where it attaches the EGR from the head.


These 3 sensors get thrown away. You can see the hard water build up on the sensors. This is on the EFI trucks as well and a wire brush will clean them up nicely and solve some issues. The holes will be getting blocked of with some water plugs. I need to get 3 plugs at the hardware store tomorrow. Less sensors, less clutter on the motor.


Water temp sensor and the only one that I will be keeping.


This big vacuum mess gets the trash can as well. I will replace it with a water plug. I will keep the 3 pronged vacuum port for a replacement for a 22re.


Was told that this is basically a heater but is not really needed. Two different styles but same plug. Also running air or water thru the metal pipe on the left let me know that it was clean in the underneath part. I don't want to take it apart so as to break the seal or cause a leak.


Port for the metal pipe. Here is what it looks like underneath. This is the one with 3 broken bolts and I used it to study the Intake. Pinky shows where the metal pipe would go and thumb shows the exit port for the water flow. I just flushed it real well to make sure no gunk is in there.


Bottom of the water heater. Is just held in with 4 bolts and a couple were difficult to get out. If I did not have another Intake I would not removed the heater as it doesn't do much good and is a step not really needed in cleaning the Intake. Baby steps to learning about carbs.

 

Dumb question: Doesn't the switch to carb eliminate the ECU?

 

Hello Nervo19... Don't worry about asking questions. I still have to ask quite a few myself. Going to carb does get rid of the ECU. The ECU controls the Injectors, Emissions, Timing and several other things. In my opinion and the reason that I am switching over is the computer relies on specific voltages and the harness and sensors are getting old and just are not putting out the correct reading that are needed.

My 85 and Mistys trucks are being so difficult that I feel it is something in the system that I could eventually find but I have a ton of time in these two trucks that are keeping me tied up that I want to get on to other projects. Never had this much issues out of 22re trucks. I will eventually convert Mistys to carb and will do a step by step on it and show what all gets changed over. There is a lot that gets changed but with a Weber, I can pull a head off in quick time and just so much easier to work on.

 

To convert a carb truck to fuel injection, you have to swap out the supply line from the tank to the engine compartment. Going from fuel injection to carb, you don't need the high pressure lines. When I first got this truck, I could not get the EFI pump assembly to separate from the line. This part is hard to find and expensive. To save damaging it, I just left it on the truck and dropped the tank. This time I cut the line and will use the EFI supply line for my carb set up. I will pull the pump assembly out of the tank and see if I can get the line to separate at a later time. A hard and expensive part to find.

On a carb truck you have a metal line and a rubber line connect the tank to the metal line. Also switching lines is a pain as you have to jack up the cab to get the metal line to run along the frame. Metal line to rubber to tank is how the factory did it. I did have to cut some of the high pressure line off under the truck but most would not know the difference if they seen it.


Here is one thing I am going to do a little different then what the factory did is I am going to move the fuel filter under the hood. Toyota sticks it outside the tank which is difficult to get to and you can see what the filter looks like. I am still doing some work on how I want to route my fuel line. What I did is cut into the high pressure rubber line and with a metal line I inserted it into the rubber line. I got some replacement rubber line from the part store and will connect to the metal line, then run a filter then to the carburetor. I think it will be a better design and look better when I get done with it.

 

The guy I restored the 86 extra cab for was a teacher. I worked on a 80 4x4 for another teacher from the same school district and he is the original owner of it. It is a very base model, no power steering or ac truck. He bought it new and it is in great condition. One that would be a great truck to get a hold of but he isn't letting it go. Not sure if you know him Tom but thought I would let you know. I helped my friend replace a blinker switch off of it and it is not quite an easy job as it took some time to figure out that the ball is pressed by a spring and a screw/pin keeps pressure on the ball.

I got the dish that operates the mechanical pump on. I know I have the spacer that Toyota calls an Isolator but can not find one so had to order one from Toyota. It should be in tomorrow. Also got a 22r distributor installed.


I got the Weber just sitting on the truck. It comes with two adapter plates and a paper gasket goes in between each one. My friend says that coating the paper gaskets is an old timers trick to making sure there is no leaks. I was unaware of that so put a thin coat of ball bearing grease on each one. Eventually I will be getting the adapter plate from LCE which is a one piece design and eliminates some possibilities of leaks.

A friend of mine used to get springs from North West Off Road for the distributor but I guess they no longer sell the springs. LCE does sell a more high performance distributor that I will be looking into later that is supposed to wake these motors up. I will be looking into that at a later time.

Weber is getting closer to getting this truck running. If all goes well in the next day or two, hopefully this thing will fire up. Here is the spacer that I cant find and know I have, grrrr.

 

i know with the 79 i have an it will one day get the weber it'll need a electric choke as the factory has water

 

Hello Cyberhorn...Kawazak636 has a greatwrite up on he Weber and he suggest the manua choke. A friend of mine has done numerous conversions and uses the electric choke. Everyone that he has done and my brothers truck is an electric choke and it seems to work great. I went with the electric choke and think I would prefer the electric over manual myself. I have been around several trucks with the Weber and it is far better then the Aisin carb. You will like it far better and is an easy conversion.

When you get around to it, I could step you thru the phone with it. I will eventually convert Mistys runner to Weber and will do a better job of a write up on it. I had help with mine this time. The conversion of the carb itself is easy with a few pictures and info.

 

I knew some 85 dont have a Starter Relay and some do. The truck I got my harness from did not have one and I did not pay attention or over looked it when I removed it. I plugged the Starter Relay into the harness and the truck would not crank. Some trouble shooting I finally figured it out. The plugs are the same but goes to another part of the harness. Thank you Toyota for some of the unneccessary changes you did in several areas including wire coloring. The Starter Relay may have been an improvement over earlier trucks but they did do some changes that still has me scratching my head.

Something I should of gotten a clue on is when I connected the plug to the Starter Reay, the wire would not reach the starter. Once I moved it to the correct plug, I was then able to connect the starter wire.

I got all of my lights working, horn, starter, blower motor and other electrical things working. Everything but the gas guage so will have to trouble shoot it. Truck will run if I prime the carburator. I need a new fuel pump as the one I pulled off of a junk motor is bad. I figure I have another 8 hours of work to get it all buttoned up before I can drive it. Getting closer.
