I am in the process of installing mine as well. Mine came with a generic style wiring harness with a relay already wired up just needing a power source to the relay and to a switch. My thought is to just power the relay and find the power wire going to the low beam headlight or parking light circuit and tap into that wire so they will come on that way. From other articles I read that’s basically how the gen 5 kit does it but uses I plug in line instead of tapping a wire. Has anyone done it this way and know what color wire would be for either or both.
