Wiring a snow plow with 9 wires, 1 harness and 2 relays. No tapping into headlights, no connectors.
One change. I put led turn signals in the plow lights to lower the current draw, then ran them into the truck turn signal fuses.
Having the plow turn signals wired into the trailer fuse made the plow marker lights glow brighter when the brake was applied (the blinkers still worked with the brakes on). It just wasn't right as a whole.
All lights worked properly last winter after I made the change.
