Need help I have a 2014 Equinox that I'm trying to install a break controller. I have everything hook up but the breaks. The red wire from the controller connects to the break switch. but witch wire it has 5 wires coming off it. I have tried probing the wires to see witch one was hot but the wires are so thin I don't want to break them into. I have check everywhere, E-trailer, local chevy store. even U-hall no help. Anyone know what color wire to hook to. Thank You Abe1951
