I was planning on taking the small circuit board out of my garage door opener and putting it behind one of the extra accessory buttons I have beside my steering column. I'll post my progress and a walkthrough type thing incase someone wants to do the same. However, I was wondering if anyone has a suggest of what I could use as a button because besides from the diff lock button shown in picture, the other 'buttons' are just place holders and don't press in. Suggestions appreciated!
