Need wiring help. Burnt harness repair te31. 1978

Post by njccmd2002 »

I need help. I bought a te31 78 coupe. And need to repair a short/burn in the harness. Donor part from junkyard not the same.

Here is the part number.

Image

Here is what it looks like

Image

I can probably trace most wires and replace. But this section over here the wires were cut!!!

This leads to the starter and the coil i think...


Image

At any rate the harness has 2 plugs to start with. Would appreciate any help or leads to a diagram to sort it out.

Image

If anyone has same harness and can even post pics of the wires in the burn plug. Would appreciate. Forgot to mention car has a 3tc, but i think wiring for most part is original

Thise diagrams are hard to read. I was hoping one with a te31 to post some pics. I brought the car back from storage to see better.

It had a lot of wires that were floating around.

Thats my biggest issue. Here in tn. No corollas in yards. No one is parting. I cannot get this harness anywhere. I got harness from an auto car. The one i bought was a manual car. Plus the car had a 3 tc engine. And i dont know what other mods done to the original harness.

From what i can tell original harness had 6 wires used from the voltage regulator. The one i bought only uses 5. Leaves one empty. And i cannot get a reference to the regulators. So see which one is Ig, B, N, F. Id hate to guess... I will keep looking.

Image

Difference in the 5 & 6 harness if because the 5 wire harness the E is not used is direct attracted the the ground

Se sample hook the wires as per this diagram it will work unless you have more power source trouble

Do this !

Ig= ignition 12V switched to regulator
B= Battery 12v continuous to alternator and regulator
E= Ground
F= field to alternator F
N= Neutral straight to alternator N
L= Is light this wire come from the cluster dash

So test you can use an bulb battery and the negative on regulator L

Electronic is no Joke but if you comprehended it its kinda fun
