I just finished wiring in a trailer power converter and attempted to wire it into the factory seven pin the power converter has a four pin pig tail that I spliced into the factory harness so it would transfer the basic functions for lights to the seven pin and replaced the four pin on the truck with the new one as the one that was there was pretty corroded. Now my parking lights stay on even when the switches and ignition are all off I had to disconnect it from the battery in order for them to shut off. The Power converter has input for brake, tail light, right and left turn, ground and of course the power cable from the battery. I have the Ground on the crossmember of the frame in the rear.I was wondering if the turn signals are 2 channel or 3 channel? this might help in diagnosing what is wrong, I double and triple checked everything to make sure I was wiring into the right wires from the tail lights and I am sure that I got those right because I tested all the turn signals and they worked fine I just need to find out what I did wrong that keeps the lights on. Any help would be hugely appreciated.

 

Are you talking about the converter inside an rv that converts 120 volts to 12 volts? Has a few breakers in it?

 

no its one that wires into my truck to power conventional trailer lights

 

are you trying to go four pin trailer to seven pin truck? an adapter maybe.

I got it figured out, Thanks for the help though.

 

When you say "trailer power converter" it's just natural for the first though to be a power converter that is installed inside and RV that converts 120VAC into 12VDC. Also, with a full sized truck, a lighting converter like this:

isnt necessary.
