I posted this in the Interior thread, but I'd like to post here as well.

I've searched for information regarding wiring a Limited garage door opener in a Base model, but came up empty.
Has anyone done this?
Also, I have a set of SRT wheels with factory tires (taken off when new). What would need to be done to wire the tire pressure sensors? I'm assuming the SRT wheels have sensors. Would I be assuming too much?
