Putting new led light bar in. The wiring harness that came with it has a cheap looking switch on it so I want to replace it. Problem I am having is that the switch that came with the lights has 3 wires, red, white and black. The switch I bought only has 2 poles (+ and -) how do I wire the 3 wire harness to the new switch?
