I had a 81' 4x4 chassis.
I have swapped on a rust free cab from a '85 and i saved the '81 wiring that run through the chassis but unforunately the plugs wont just plug up.. so i cut the wires and matched a few of those colors to the cab wires that hang out,

Now, I've got 4 or 5 together but,I still have some left & I don't know were they hook up to.

I was hoping someone here tell me where to or what these wires are for.
They are as follows:

Pink/orange tracer
Blue,
Red ,
(2) Brown wire/White Stripe,
Black/pink Stripe...

points ignition,

I dont think my distributor is a electornic...
I do have the ignition module

The engine I have came out a 70's something
The dizzy has one black wire coming out of it

Does it go to the - on the coil ?

We're going to have to split this thread up.

You must realize you went backwards with picking a wiring harness?
The 84 will have numerous differences.
Electrical harness ?

What we need to help us.
1) What engines were in both?
2) Is this the main wiring harness under the dash,Under the hood (along firewall) ?
3) Physical Location (where along the harness) of the extra Wires?
4) Computer Box ?


We'll get to the distributor & ignition later.

 

what do u mean , backwards? the cab and the front clip i got this '84 or'85 orginally had a 5.0 /302 engine but i only had it with cab and front clip to do the swap,l also the wire harness thats i have plugged to the back lights and through the chassis is a '81 which my chassis is a '81 but they wouldnt plug up with the '84 or '85 plugs thats come out the firewall so i cut them where they meet and wire it the way i see it but i have a few wires hanging unknown what they do or where they go, i dont think i have the computer box in that cab whihc i took out which i dont think i need it . since i m running a carb on my 429, but far as now i got flasher blinkers cab , lights working now just fine cept those wires i have hanging from both ends i jsut wonder where they goes or what they do, i know i dont have the back up light working whihc is a brown wire and the fuel vavle selector which is also another brown wire, where i cut then in half is where right belwow the firewall and the chassis thats where i cut then and try to connect them...cuz the plugs were easily plugged up cuz of the different years and sorryt again the '81 harness I used was equipped with 351M eng. also this is a 4x4 truck, sorry again i m just bad at explaining but hope i ll get engough info to get some help too... those wirees i metuioned i have left over so those are the wires thats i have left over on both endeds so hope someone can tell me what they are over there... thenw e ll go to the ignitions and stuff

 

I was under the impression you cut up and are using the 81 wiring harness ?

All I meant is : The 85 wiring harness would have more options available than the 81 would


So, what you're saying is : You are using an 81 harness with a 85 harness plus You cut the wires to mate them because the connectors were different.
This wire cutting took place just below the firewall where the harness start to head its way toward the rear part of the truck.

Frame harness can carry :
1) Fuel tank(s) wiring
2) All tailights & marker lights
3) Trailer connections (if so equipped)


I'll have to type out the wire colours you mention and post it here, as it is really difficult to understand the way it is.


EDIT:
Pink/orange tracer {Could this be faded red (pink) with orange ?}
Blue,
Red = {Front Fuel Tank....? }
(2) Brown wire/White Stripe, {Dual-Tank Selector}
Black/pink Stripe...{to Windshield Wiper Motor}

Could this be Pink with Black Stripe instead?
{If so that is the fuel pump cut-off }
