Have a '61 261 w/12v starter going into a '37 that had stomp start and original "on-off" key switch w/ wire going to a new 12v ignition coil. The solonoid on the starter has a lug for battery connect, and 2 other terminals one marked "R" and the other marked "S". I have an extra hole in the dash where I intend to install a momentary contact pushbutton that has 2 terminals to replace the stomper. How do I wire the p/b and starter up. As always, thanks for your responses
