I would think that you can relocate it into the cabin no problem. Im going to need to do this, as my strut bar doesnt allow it to be mounted in the stock location now.
The harness looks long enough to get it under the drivers dash at least. Im thinking big hole and gromet.
Ill get some pics of it when I get around to doing it, It might not be for a while tho.
however, Id love some pics of it done, if anyone has, so I have something to go on.
^^I got your instructions from Carrie, Im doing the relocate as soon as I get my new seats installed.
Its pretty easy, i got some pics of mine if either one of u want to see how the ECU sits underneath/behind the peice. but cant be too hard for you to figure out if 7 people that i know of have it done lol
