I have an aftermarket flatbed on my 16 3500 diesel dually... and the left side brake lights/blinker went out. It appears, i have a bad wire or loss of power somehwere in a rats nest of wire harnesses that can't really be reached due to the flatbed. I'm going to tap into my trailer outlet and splice into the tailight harness. However I've not been able to determine which wire i need to splice into. There's 4, (white, black, white/brown(or orange), and white/blue. anybody know? Thanks.
