recheck the wire harness at the plug in the blue wire is your power wire and that is the pin in the middle,your white wire is your ground wire and should be the larger pin on top of the blue wire.the red wire is not your hot wire its your brake lights,brn is clearance,grn is rt turn and yell is left
