Help with wiring accessories!
 

I had an idea that I'd like to try. The problem is that I don't know exactly how to do this. To keep my interior clean and for safety reasons, I'd like to have 1 power switch activate line lock AND trans brake. That way I can flip a switch and deactivate my line lock and tranny brake while on the street. Any ideas on how I could do this?

Can anyone help or is this a question for the drag forum??
