Turn signal problem.

I still feel strongly that your problem is with the tail light circuit boards I had a very similar issue with my truck when I bought everything worked fine when lights were off but when turned on it screwed everything up besides the circuit boards are cheap I got mine from AutoZone for like 27 bucks for the pair.... I'm not saying that is for sure your problem but thinking it could be.... also have you checked all the bulbs in your tail lamps

I dont have circuit boards man... My tailight housings have 3 seperate bulbs. Any idea of where the grounds are for the rear electrical wiring? Thats my next course of action

There should be a ground at the frame under the DS rear taillight. If not, check for mods to yer trailer light wiring to see if the ground has been moved. Either way u should have a ground at the back of the truck.

I never thought of that! The PO had hacked up the wiring and it looked like he tried to install a trailer wiring harness. When i got the truck the license plate bulbs werent working, and i had to fix that. I bet something has come loose. Thank you very much guys! Ill check that out tomorrow.
