I could write up a breakdown of the switch build but it was not simple and I dont have many pictures of the process, just what you see here.
I went though my first PC board experimenting and then was successful with the second one. At this point you would have to use the Race ready system, or source the exact switch for it to work.
Whats funny is that the switch they use is an old OEM BMW window switch. I could defiantly help someone trying to do this exact thing. But with a different switch would come more experimentation.
I am more than willing to help anyone local with this solution.
