Hi everyone,
I have been pouring over the wiring schematics from Coolerman and others, but cannot seem to find one that is an exact match for wire color / directions. Maybe this is because its is a fun transition Sept 1974 FST, or maybe because it is a fun CA factory smog vehicle!
Anyway... the previous, previous owner had wired in a clunky trailer wire harness and I am trying to delete that harness while making everything work as it should.
The attached picture is where I am currently at. I do not have running lights (bulbs and leads have continuity, I have checked the running light grounds), I do not have any lights in the rear (Brake, running, reverse, signal)
Nothing from this harness is connected to either grounded bolts. I assume this is problem #1.
I am trying to figure out:
- what should be grounded?
- Or do individual light housings properly ground everything, and no additional ground is needed at rear cross member?
- judging by factory bullet connectors, did this have a factory trailer harness wired in, or was this just for the rear license plate light?
-Lastly, what wires need to be connected where!?
Here is what I have followed from original wiring diagrams:
GB - Driver Turn signal
GW - brake lights
G - Side marker signal lights , running tail lights , license plate light (which I don't have physically have on the vehicle
GY- Passenger turn signal
GO- Something to trailer socket change over?
RL- Trailer harness wire? Reverse light wiring?
Thanks in advance!
