I have a 2002 Range Rover 4.6 and I connected an adapter to convert a 4 wire brake setup to a 3 wire. I found the factory harness behind the passenger side tail light and all the wires check out properly. I hooked everything up and all of a sudden I lost power to the trailer plug for the brake lights and the turn signals. The running lights are working perfect. Any Ideas?

Is there a fuse that powers the trailer light harness?

Everything else is working perfect on the car. The tail lights work perfect along with the turn signals and brake lights - it is just the trailer harness that went dead...

See attached from RAVE tech manual, if you have always wanted your own set it is free to download below. There are multiple fuses and fuse links involved. Each is listed in the text.

 

Thanks so much.. I figured it out. There was water inside my tail lights on my trailer causing it to short. I replaced the tail lights and everything works perfect.

I really appreciate your help...

P.S. is there any remote systems to replace the factory keyless entry? Mine is also wet and rusty.
