I have the Ford 600 Plus Alarm installed on my car. The blinking light next to the rear defrost is red and I want to change it over to blue. I bought a led blue light off Ebay. It has 2 wires, a black and white one. The red light on the car has 3 wires red, blue, and green. How would I go about tieing these in togther or do I need a light with 3 wires?
