What I have is 07 379 having wiring issues. Starting with the basics im running single bucket headlights along with the led light bar as my front signals. I have 2 round double faced ones off the mirror as turn signals. and for the rear I have 4 in my center panel wired as just running lights and the mud flap brackets with 3 lights as the running lights brake lights and turn signals. The rear turn signals only work intermittenly when that happens the brake lights also dont work. I have had issues with the front not working sometimes. Could it be the front led bar is causing the rears to not function??. The midpoint signals also work fine. The last time they didnt work it was just the rears. The 2 fronts worked.

It's the multifunction switch. Or turn signal switch depending on which parts man you talk to. The brake lights not working at the same time gave it away. Pretty common problem

so the switch off the column??
