If I remember right, there are 3 wires going to your OE OD button. Red,black,and tan color with a white stripe. The tan one is you OD wire. Hook that up to a switch. You OD light won't come on so that is why I have indicator lights for my switches. I'm gonna take apart my console again soon cause I need to do some stuff so I'll try to take some pics then and look at how everything is again.
