Don't let this guy touch your electrical. I paid him over $1,000 to install a trailer plug and break controller. He insisted he buy all the parts. Well, finally got around to using it, nothing works. I tore apart the work he did and it was a mess. Wires not properly spliced. A breaker and two fuses missing (never installed, wired straight to battery). Didn't even bother to connect the aux 12v on the 7pin. The wires he tapped, you didn't need to, you just buy a $20 harness for the light. The worst part is, on fixing it myself, I found existing factory wires for a ground and brake wire all of 6" from where he created a new ground point. And it looks like he spent at least an hour connecting the break tap in some weird spot that wasn't even pushing enough voltage. The brake controller he put in, is completely fried on top of all that, likely from the lack of fuses and breakers.
