What happens if you install the mopar 7 pin and don't get it flashed? I ask because i'm having trouble getting my trailer lights working. I have removed all of the wire loom to check for a bad connection but all are fine...could the relay in the line go bad? The problem is my passenger side turn signals work but when I try the drivers side nothing works, not even the jeeps turn signal works...I unplug the harness and my Jeeps turn signal works again?? I just put brands new lights and wiring in the trailer so I know those are good but this one really has my stumped...any info our thoughts would be appreciated!
