E type... I've been thinking about doing this... just haven't tten around to it. Anyhow whether its oil filler or not that should work. All you need is power ground and signal. There is a reason I haven't done it and it has to do with the wiring uust cant remember what that is. When I'm with my jeep spending quality time I will look into it and get back to you.
