Trailer Lights and Wiring Harness

I just bought a leftover 2005 KC XE with off-road package. I had the Dealership add the tow package. Well I just tow my trailer for the first time this weekend. When I left I made sure that my trailer lights were all functioning properly. About a half hour into my trip I noticed the lights were out. I Stopped at a truck stop and bought a light tester and I could not get any signal from the pin out. I tested the fuse in the fuse box under the hood and It was fine. I am wonduring if it could be one of the 2 tow relays, or if there are anyother fuses I should check.

--Thanks Dave

I'd say that or a bad ground. Does your trailer use the ball as a ground? If so sand all the rust and or paint off of the receiver, and ball.

I'll give that a try. I did use the tester on a good ground and still no signal from the plug.

There is a TSB about replacing a BCM harness in connection with the electrical wiring for the tow hitch wiring connector. I'm not sure if it applies to 2005 or only 2004.

www.nissanhelp.com You can look up TSBs, etc.
