I'm gonna take a stab at this since its still fresh in my head... most of them are on E5 in my case... STA, IGSW, BATT, +B, (the etcs wire E5 pin 2 , 15 amp fused per you !) which mine stll ran without it hooked up but you'll need this to get the full throw of the throttle, STP, and FC. There were also a couple of wires from IK2 they were red /white , but if you have a 4 runner they're probably going to be blue / white. (These power all the engine sensors/ controls), and they will be hooked to switched power .. See if this works for you. I played with the MREL quite a bit but ended up not hooking it up to anything.

 

this is using the 1992 fuse box with a 2003 tacoma manual 4x4 ecu

 

Thanks Dan! I might go back to the 1990 fuse box. I only have to add 1 fuse after all.

The swap just got more interesting!

 

a motorhome with a supercharger ..... priceless... haha How much you get that for ? Was that an ebay deal? Whats your plans on tuning?

 

I got it off ttora forums for $600 shipped. I might go with megasquirt if I ever get this thing running.

So new problem! Its cranking sometimes if the starter aligns with the fly wheel. We had to turn the fly wheel manually and it would crank. Also its not starting!

Just going over all the wiring. I didn't use mrel, but the fuel pump is kicking on. I guess I should try a spark test. The ecu might have a bad ground. I'm pretty sure the igniter doesn't need to be grounded to the body since it has a ground wire.

 

This is all really cool! Great work! I'd love a Dolphin/Spirit some day....

 

Dude this is a ridiculous build. good work.

 

She starts!!!!!!!! Now another question. Do I need any electrical connections to make the auto tranny work?

Please help me out guys I need to move this thing!

Thank you,

Thanks... its been a long journey since I tried the 3vz header install on the rv.

 

The problem with the starter was I didn't have enough amps going to the newer 4runner's starter internal relay, which I thought would be the same as the pick up. The power source for the starter was from the 40 Amp fuse, which is connector C1 pin 10. This goes to connector ii1 pin 3 then goes to the neutral start sw. From there it comes out the connector ii1 at pin 1 and splices to the ecu and starter.

Pin 10 of connector C1 is a pretty fat cable. I don't want to put to many amps through the n/p switch, so I am going to have to add a relay to send more amps to the starter's internal relay, which is how the 02 4runner wiring diagram shows.

I wonder if my oil pump is done for the transmission. We might have to put another quart in there to see if it builds pressure. From what I am seeing the transmission doesn't need any electrical input to work. Oh well at least I got plenty of practice pulling the tranny .

 

not sure about the tranny as mine was a manual 4x4 ... isn't it nice to hear it run!

 

It is nice to hear it run. Got stressed a little bit when it didn't start right away. The auto transmission fluid looks low, so that might be the cause of low pressure. I hope! I need to either add 1 fuse and relay or switch to the 4runner fuse box.

The wedding is right around the corner and I want to roll out with the rv, but its sure is getting close.

 

Hey guys,

Here is a picture of the engine bay in a running condition. I still need to wire up the trans and dash lights. I have the next two weeks off for the wedding and might use Tuesday to finish up some wiring. Any advice on getting the ecu to the stock location?



I am going to Pick Your Part on Tuesday and getting the relay junction box that attaches to the fuse box. They usually come off 4runners with a/c condesnor fans (I think). This way I'll have a relay for the starter. Also going to pick up fuse terminals for the 15 amps I need for my ETCS.

 

The new starter plan.



The relay box I was going to use.



Wired it to the green relay.



Found out that when the coil had voltage it open the circuit. So I moved the terminals to the black relay, which is the correct style.

The new splice goes to the 30 amp fuse, which then goes to the relay.





Finished!



I still need to get the 15 amps to the ETCS, which I can probably knock out before class tomorrow. The RV is now moving! The tranny fluid was just low. Therefore no pressure. Its all coming together now.

 

Use the front bracket from the 3.0 ecu and remove the rest. Tape the left over holes in the ecu and you should be able to mount it in factory 3.0 spot. I have done so many times

 

Thank you... Going to try to clean up the rats nest soon!

UPDATE!

Went to B and M Mufflers in Garden Grove, CA and got my the rest of the exhaust done. I got to say they did everything the way I wanted it for $200. I was dreading doing the exhaust because I wanted it routed between the torsion bar and frame, under the cross member and over the drive shaft to the stock muffler. This also includes installation of the donors stock cats and o2 sensors.











I assume the supercharger is going to choke on that stock 3vz pipe after the 2 cats, but I'll chop that after I pass the smog referee.

Still some wiring to do. I need to get the ecu in the cab and wire the speedo, tach, shifter indicator, and ect. There is probably something else, but its getting much closer now!

Thanks for looking!

Wow, Navy, NICE SWAP! LOVE the Yota-RV's! I keep seeing dolphins, but they're asking a bit much IMHO! lol. I'd LOVE to find one, so I keep looking...but WOW, what a great idea on a swap to get the power you need without going TOO nuts.

Admire you swap guys.... HUGE respect for that undertaking. Like anything, I suppose, "If you have the drive to match the necessary ambition.... IT'LL GET DONE~!" LOL.

Watchin!

 

Thank you Chef!

I like your 4runner build. If you can make an engine bay look like that you can do a motor swap no problem.

I would keep looking on the rv. We spent $10,000 on a 1991 toyota itasca with 24,000 miles. You can spend much less if you get one with more miles.

Good luck!

No update yet, but I have been messing with the heater hoses because they bug the crap out of me. I am going to have to go to pick your part on monday and pull a corolla 90 degree water valve.
