Haha, I can understand where you're coming from, Eddie, especially with the problems you've had with your harness.

A couple of things to consider:

(a)Don't bother with the LED lighting
(b)It would be a straight swap for the starter button you have, so no new wiring
(c)If you really did want the LED then all you have to do is pick off a supply from any live (even your master solenoid before it goes to the VPX) and then the other terminal just goes to ground. It's not powering anything but the LED in the switch housing, so it'll draw a teeny current.

But I can empathise with the fact that you don't want to change stuff
