7 wire plug is giving me headaches. everything was working fine pulling trailer with breaks.
no longer have turn signals to the trailer. I've tested that i have power at the back of truck from 2 wires: power wire (red) and running light wire (brown). I believe my problem is related to the brown running light wire. I have power to these 2 wires no matter what signal, 4 way flasher or break function I use.
All fuses are fine, however there is a newer wire connection running from back of light control in truck to a fuse (i assume its jumping power from a vacant fuse)
All wires appear fine, no cuts, nicks
Any help would be great.
