There are 3 wires going to the OD button: RED-Black-and tan with a stripe. The tan one you don't need. It just turns the "OD off" light on in your dash. When thered and the black are connected the OD is on, when they disconnect, the OD turns off. These are the 2 you need to run to a switch.
This is going from memory so my story might be damaged, but I think thats how it goes.
Oh, and everything I have is 2 inches taller than most!
