Ok so I wired everything up. But I am having a very difficult time finding the speed sense wire. I know it is the purple and white wire behind the fuse box. But how the hell do I get to it? There are so many wire and harnesses connected to it I can't get to the back. I also need to find the The reverse gear signal wire. Where when I put car in reverse it senses it. Does anyone know where that wire is?

 

try catching it behind the cluster...

 

ok, the reverse wire is Red with a black stripe. I think it is a 22ga wire, down in the driver side kick. what I did is test the wires at the tail lights and worked my way up to the front of the car. If you would like, later I can take a picture of the wire I tapped into.

As for the Speed pulse wire, I didn't use it cause I dont have a nav unit. there are ways to test wires to see if there are right, it is just a little hard to explain.
