No left turn signal on trailer plug
I have a 96 F250 with no power to the the left turn signal post on my trailer plug. Tracing back up the wiring harness to the pigtail, I have no power at that point either. I am wondering if I need to run a new wire all the way back to the front of the truck, or whether I could just remove my left rear tail light cover and splice into the wire there and run it to my plug. I am not sure if I would be affecting any fuses or electrical capacity by doing so. I really don't want to have to try and find the break in the wire between the pigtail and the front of the truck.
