Alright, so the rear lights on my Camino have been screwy since the get go when I got it. Various issues with them too numerous and long forgotten to bother you with. But I finally just outright ordered all the parts to replace everything wire related in the rear bumper. Pigtails, housings, ect. And for the life of me I can't stand how every Camino I have, the prior owners put a trailer hitch and crap on it. So I was very happy to cut that out of the system. Anyways, so I'm trying to rewire it myself, and having a very frustrating time.
I've been trying to find some diagrams online to wire my 76 up to. But the plug in the wall on the driver side that the lights go to, doesn't ever match just perfect. MY plug has a black wire, a dark green wire, a yellow wire, a brown wire and TWO light green wires.

Every diagram I find only shows ONE light green wire and they show it being split to the two reverse lights. But I have everything else connected like the diagrams show, everything is grounded, brown runs to all of the marker lights, and yellow to left tail light and dark green to the right tail light.
What I've been doing now is, seeing as I have two light green wires, I just run one to the driver side reverse light, and the other to passenger side reverse light. And what makes this so awful is that everything works, sort of. Tail lights
do come on when park lights or headlights are on, if I push the brake, the tail lights get brighter, if I put it in reverse, the reverse lights come on. I go to turn on the left signal, and the left tail light just gets brighter, but doesn't blink, same with the right signal. I have checked the blinker fuse, and it seems to work for all intents and purposes, I can both hear and feel it working, and even the 4-way emergency lights blink strong. But not the signals. I know I wrote a book here. But any help someone could offer would be very much appreciated. Thanks anyways.
