You are gonna be looking for the purple wire behind the instrument cluster. You have to remove the entire drivers side dash to get at it. Start at the door, and work your way in. there are way too many screws to remember where they all are but if you take your time and remember what sizes go where, it's not too difficult. Just a heads up, the surround for the instrument cluster and the plastic that is on the top part of the dash are fused together. Dont' try to separate them or you'll be in there with the epoxy or hot glue as super glue will not hold it. Weird plastic combo.
Also, check out this thread. It's pretty much exactly what you are trying to do but more in-depth.
