87 transam tailight wiring diagram

Hey guys, Im in desperate need of a wiring diagram to repair my car.It was hit on the driver side quarter panel about 6 months ago and i was just able to have the body work done.But now the lighting is all a mess.Most of the sockets were destroyed on the driver side so i had to buy new sockets.I tired to connect them but obviously some of the wires are not connected in the right spots.I got some bulbs on with both elements light and some arent when the parking lights are on,the signal to the left no longer flashes but it does sometimes depending on which bulb is taken out,no brake lights on that same side and no brake light on the outer right bulb.If anyone has an exact layout of what everything should be i can fix it instead of guessing how it should work.Thanks in advance for all your help.

I got the same car with the same problems!!
I cant figure it out either!!
I just got the car and when the brakes are pressed my left lights are brighter and the reverse lights come on? and when i use the hazards all the lights in the back flash , left is brighter than the right, it is like the right isnt getting that much juice? What have you tried ?? any luck? if you have any suggstions it would be appreciated!! Thanks Rick

im sure i could figure it out eventually but id rather not go through the hassle of chopping and slicing wires all the time before i get it right.my reverse lights work just fine so thats a start and the left side flashes and brakes except the outer bulb.the driverside is the most headache.if no one on here has a diagram then ill play with the wiring myself and ill be sure to let you know what i find.

I swapped in newer style tail lights (89 Formula) for that harness in which you have. Let me tell you, i had a hell of a time getting those wired up. What i would advise you to do is pick up the whole harness from a junkyard (like $10 or less) and splice it in over the left rear wheel well underneath of the interior plastics. Then next replace your flasher relay and get new bulbs. That is a fast, simple and foolproof way to correct the problem. I tried splicing the individual sockets in and had a difficult time getting them right. Mine exhibited the same type of problems that yours has now. Worth a try, hope that can help. - Bob

Well i was able to get a diagram through some sources and wired all new sockets in place..it was easier than i thought and if i payed more attention to the way it was wired from factory i should of figured it out a long time ago.its really only 5 wires in there and the easiest to find was black for ground,then the brown was for parking lights,yellow was for the left turn signal/hazard/brake,light green is for reverse,dark green is for right turn signal/hazard/brake if i remember correctly.but i can double check later
