Howdy-
Hooking up my trailer wiring. Have 7-pin connector on tow vehicle ('97 Nissan Pathfinder) and trailer. Checked tow vehicle connector with tester and found all in working order. However, the trailer connector/wiring harness is not color-coded according to the colors noted on www.etrailer.com and in diagrams on this site. I tested the various wires on the trailer harness though and identified the turn light wires and running lights and ground, etc...
My problem is this...All running lights (including tailights) work on the trailer when I turn on the parking (running) lights in the vehicle. Leaving the running lights on, I then tested both Rt and LT blinkers....both operated correctly. However, when I then depressed the brake and then tested RT/ LT blinkers, the left (drivers side) blinker operated, but the right blinker did not. It just seemed to have the tailight filament lit and the brake filament lit.
I also noted that when I disenegaged the brake and tested the blinkers again (they both worked again) that all the side marker lights and the non-blinking tail light dimmed noticeably in time with the blinking tailight.
I did not ground to frame but ran a dedicated ground wire to a bus bar.
Any ideas where to troubleshoot here. I am sure it is something stupid that I overlooked...I am just too tired to see it myself. I have read about the tail light converter, but don't know if I need that here as the left tail light & blinker/brake light seem to work.
Thanks!
