1999 Ranger trailer tow wiring

I would take the plug apart and see if a wire was loose to start with, if you are absolutely sure no fuses are blown, either under the dash or under the hood.

Thanks for your post. I have checked as far as where the adapter harness hooks up to the main harness under the bed. No fire coming from the main. Dave

Don't waste your time under the dash or the hood. He said *ALL* truck lights are working. The problem is between where the trailer wiring splices into the truck wiring at the rear frame and the inop brake light. If the LH trailer tail light is also out, I would start by looking for an open ground at that light.

LH taillight works. Lh turn/stop are inop. Also, the trailer lights are fused separately from the truck lights at the dash fuse panel. Dave
