anyone ever do one of these mods? if so, was it easy? where did you mount it?

 

You could buy a race kit or make your own. Figure 1 switch, a few relays, 1 push button, and some wire. I mounted my button by the other dash switches, but you could really put it anywhere inside.

 

do you have pics of your setup?

 

My setup is slightly different than what you are doing for your car. Do not ask for specifics since I will not share them, but to do what you are asking is simple, power up the cylinder wires and use the relay/button combo on the starter wire.
