I purchased new trailer lights and wired them. They came with two marker lights as well. I believe the wire colors are universal so I will describe my install. Brown and Yellow to driver side, Brown for TAIL and Yellow for STOP/TURN LEFT. Green an Brown to passenger side, Brown for TAIL and Green for STOP/TURN RIGHT. Marker lights hooked to Browns. Passenger side works fine. Driver side has issues. When I turn on left signal, it blinks but not in unison with truck signal. No big deal except passenger side blinks in unison. Both brake lights come on without headlights on. When headlights are on and I step on the brake driver side lights go out. Also, when headlights are on, driver side is dimmer than passenger side. Any ideas? Fuse, ground, crossed wires?
