and check the fuses if its poppin em you have a wire rubbing shorting out on metal. if someone had it apart thats probably the cause because of him just not routing and protecting wires properly.

In my experience with older vehicles, about 99% of the time it seems to be the ground. I think someone else suggested this as well.

Do you mean you cut out the trailer harness, or did you go in and re-connect the original wires everywhere it was spliced in.

The problem with home made trailer harnesses is at the splice point, they get corroded and stop conducting. So you have to redo the connection between the original wires, not just cut the trailer harness out.

Well he just took the rubber from around the regular wires and just wrapped the trailer wire harness around that so he never cut the wires

yeah i would check that out and alot of times people dont realize unprotected wires can rub and short out, which is also a fire hazard so i would learn that truck inside and out and make sure the previuous owner didnt leave any wires exposed. that could be one cause, especialy since the harnesses were modified.

It appears to only be one circuit so it is either a fuse, a switch or a cut in the line.

If it is a fuse it is worth trying a new one but check that all lengths of white cable in the rear portion are properly insulated.

If you mean the one in the photo it appers to be spliced on to a green wire, this is the right hand turn signal wire. Or have I seen that wrong? Anyways that is the only green wire you should have at the rear.

You're not providing much useful information for troubleshooting and the pics aren't a lot of help either. Sorry, not trying to be jerky. Just being honest.

My advice would be to probe the sockets for power then move forward. This is one of those times when you need a multi-meter or test light instead of just inspecting the wires. Multi meters are like $20 and will tell you a lot more than a test light, it's a tool that belongs in every home mechanic's toolbox. Good luck

Tfain, I know your frustrated and you want this to work like yesterday but you are going to have to listen to people on here.

I sent you over some diagrams earlier in the thread and it clearly shows what that wire is on the diagrams and here is a hint, it is a ground. I pulled it up and found it in 5 minutes.

Again, I'm not being a hard *** or mad, I've been observing this thread.

Wiring Gnomes are always fun to deal with but you got to establish the factory wiring from the newly introduced rats nest. Start at the tail lamps and work backwards. Get the manual out or diagrams and start following the factory color coded wires and fix the splicing, patch up exposed wire sheathing, clean/fix grounding points or make news wire looms.

Earlier in the thread I mentioned the PO had used lamp wire on my pile. He cut the actual factory wiring and ran a wire to the brake light switch and one to the battery, with lamp wire. It was amazing, though it did not for some reason.

I wound up making my own harness and looms from the tail lights up to the connecting harness block, brake light switch and headlight switch. The wiring was so far gone that it looked like a shotgun got a hold of it. Trust me, I know your pain and frustration.

Take some breaths and start basic. Get a testing light and multimeter, these tools are highly valuable, I cannot stress that enough, along with what has been stated by others. Oh and wiring schematics!!!!!!!
