83

Part of this was posted by others over at the Marlin site, but I added to it & figure we could use our own swap thread over here in the pre-84 area. I think '79-81 trucks are different, but if you have an '82 or '83 with the "newer" style gauge, this will work.

**EDIT: The person who made this list came up with the numbers by counting every slot in the plug. The FSM numbers them differently because it only counts slots that have a wire in them, so don't try to compare the two or you'll get confused like I did!
It also seems better to use the wire #, as opposed to color, since some seem to be different. I'll post at the end of this thread what wire color I've got in what #slot. For that part I used the numbers from the FSM, not from this list below. Feel free to post here or PM me with any questions.

SR5----------Non-SR5---------Wire Color----Function

1<-----------------1-------------->GY------------>Right turn signal
2
3<-----------------3-------------->BR(B BR)------->Speed Sensor (-)
4<-----------------6-------------->GL------------->Speed Senson (+)
5
6
7<-----------------23------------->YG-------------->Water Temp
8<-----------------9-------------->RW-------------->Panel Lights (+)
9<----------------15-------------->YR--------------->Fuel Gauge
10<---------------12-------------->Y---------------->Ignition switch power
11<---------------21-------------->YB--------------->Oil Idiot Light
12<---------------22-------------->YW-------------->Charge Light
13<---------------14-------------->WB-------------->Ground
14<--------------------------------------------------Tach-must run a wire
15<---------------17----------------GB---------------Left Turn Signal
16----------------16----------------RB---------------Panel Lights (-)
17
18
19<---------------11---------------G-------------------4wd

23<---------------13---------------RG------------------High Beam
24<---------------20---------------GW-----------------Brake

So if you get an SR5 cluster and simply plug it in to your truck, any of these wires that aren't the same number won't work. When I just plugged my cluster in, the right turn signal was all that worked. So you need to pull the wires from the corresponding number out of the plug and re-insert them into the SR5 location.


This shows what the back of the cluster looks like and the wire numbers. It also, if you can see it, shows you where the separate oil & volt cluster hooks in.



So to get the oil gauge & voltmeter working, you need to splice into the main cluster wires. You could get away with just splicing into hot wires here and there, but I liked doing it the way it would have been if it had been wired for it from the factory.

Cut & labled


Connectors


My voltmeter ended up having some different wire colors than the FSM page listed, but they were all in the right location in the plug, so it was easy to figure out.
What I came up with after looking over the diagram is this, as far as what wires to tie the mini-cluster into:
Mini-------------Main
19 & 21(oil)---------->17
18 & 22-------------->6
21(volt) & 23--------->12
24------------------->Oil sending unit (SR5 model for GAUGE, not idiot light)
20------------------->Ground

Notice there is a #21 in each gauge for some reason.

If you want the oil idiot light and gauge to work, you need both sending units; one hooked up to the main cluster (switch), one hooked up to the new oil gauge (gauge). I just left the idiot light out..

Splicing into main cluster


Connecting to mini-cluster (I used 16 gauge wire)


I'll need to pull the part that connects the wire to the oil sending unit off a truck in a junk yard & splice it in, but for now I just have the wire wrapped around the sending unit and it works fine, but I'm guessing it'll eventually vibrate off if I leave it that way. That's it, mine works great.

this is great how ever its still confusing first you give what some other guy did which is great but what pin or slot did he start his count second the fsm is even more confusing so here is what i got i have a 1983 toyota pick up 4x4 stock no tach instrument panel and a sr5 instrument panel i think has tack all dummy lights from same year im pretty sure. that i want to put in my truck but only my right blinker works nothing else so how do i wire my plugs to work with this gauge it is the same gauge set u show above in the book

Did you read the post? Your symptoms are exactly what I describe. Read it and if you still have specific questions, feel free to ask.

To be honest, I don't really remember anymore. I remember that I figured it out, and I'm no rocket scientist. Look through the info, and figure yours out with what's there. They are not all the same, so there's a certain amount of just figuring it out on your own.

Almost looks to me, looking over it and seeing where the gaps are (no wires in the plug) in the FSM, compared to where he has gaps on his list (something you could also do yourself..), that he started with #1 at the opposite end that the FSM does. So his 1 is 13 on the FSM, then you go across from there. Just compare the gaps. Otherwise, between the FSM and that chart, and a little trial and error and frustration, you'll figure it out.

Maybe try comparing your wire color and FSM slot numbers to my last part of the post and see if that matches yours. Maybe you'll get lucky:

i got an 82 with no tach. would really love to add a sr5 gauge with tach. best place to find a sr5 gauge? just a quick question. do you have to run a wire for the tach?

also where can i get a set of those amp/oil gauge as i dont have those

83

Internets.

Here, craigslist, marlin, pirate. The "practically anything you want" thread at Marlins site is where I found all my little bits and pieces, including both clusters.

I had to run a wire for the tach. With older trucks, you just plug in the new cluster and you're set. Not sure about an 82...I only know my 83.

if you don't mind I am gonna add this to my mini FAQ
nice job

83

Awesome. It's a little scattered and not too straightforward...but I think it'll get people there.

Zach,

Any chance you could get a higher resolution pic of the cluster wiring page that you posted above?

83

Yes, give me a bit. I'm out in faaar eastern MT for work this week. I'll try to get better photos over the weekend.

JustDSM

No rush.. My truck isn't going anywhere ANYTIME soon :/ But thanks for helping us (me) out with the service manual scans.

83

Ok, I'm keeping these their original size so you can see things better...let me know if I should shrink them a little.

JustDSM

That's perfect IMO!

Thanks so much!

83

No problem

Chickenman

You ran a wire for the tach, but which wire on the coil did you connect it to? Ive looked at diagrams and my wiring colors dont seem to match the diagrams, so why not ask someone who has done it?!

83

Don't remember right now but I'll check. Better yet, do a search. I found all the info I need in my FSM and on the internet. There are a few threads that talk about how to connect a tach wire to the coil, both here, and probably at Marlin and/or Pirate.

I'll try to remember to check my truck sometime this week, though, and maybe take a photo.

Now I have a question my truck came with the voltage and oil pressure gauge but it was not the US gauges it was CA gauges . I found US gauges tried just plugging them in and they don't do anything.

83

No idea...

funcrazy1

You think different wiring?
