Please help with wiring...
 

Ok got this " ignited performance " push button start. I get stuck and scared with all wiring stuff.
I think I found the starter wire from the key.
Dark green with yellow stripe.

Then I need 2 12v power sources. Both with power when key on. Where can I find that? One says to be 18 gauge and one 12 gauge. Why they different?

When I find the starter wire can't I just cut it then run the rest to the button? I dint really want the key to start it. Is it that simple or a lot more complex?
