Want to Add A Start Button on Dash, ...keep bending my key Options

[7TPorsh]

I keep bending my key starting my car. Is it hard to add a button on the dash where I can turn the ignition on with the key but push the button to crank the starter?

I have the button with two terminals. Is it simply one goes to 12v (fused?) and the other goes to the starter? or do I need to mess with the ignition switch?

Gary,
You could do it with a start switch on the dash, but use a switch that handles at least 40 amps. Initial solenoid current is 35 amps. The better way would be to add a relay such as McMark on this site offers and also replace the ignition switch.
I suspect that if you were to open up your ignition switch after replacing it, you would find arc damage and carbon build up around the starter contacts. This comes from the high inductive spike from the solenoid's collapsing field, and from the initial arc from the two contacts suddenly conducting 35 amps. Using a remote relay saves the ignition switch from these damaging events and transfers them to the relay. Relays have different alloys in their contacts to help suppress the arc damage.
