What steps do I take to change mine out to another one? Thanks

Funny I just took mine out yesterday. Not sure if its different for your model but for my 92 you just have to remove the kick panel underneath the passenger side behind the glove box. Look up there and you'll see a bunch of wire connections hooking into a silver looking box thing. There was one bolt to remove that allowed me to slide it out after removing the 3 connectors to it.

Hope that helps.

heres the connectors


and this is the box when its out

Do I just pull out my chip and put it into my new box? Thanks for all of the help guy'*
