1999 Cherokee XJ Trailer Wiring
I've searched this topic but not getting what I need. We added a curt trailer hitch and plug in wiring harness to our 99 XJ. It all went together easy enough but when I plug the trailer in the only thing that works is the tail lights. I've got no turn or brake lights. The trailer is fine as I hooked it up to another vehicle and everything works. I've got power for each function (test light) at the plug but once I plug the trailer in, I get no turn or brake at the back of the trailer. I've also verified I've got wires matched up on the plugs. Any thoughts on where to start diagnosing this? Wondering if the converter is bad as I read happens but it works at the back of the Jeep so I'm not sure. Thanks!
