Lighted T/C lock switch?
Hey guys, I have a quick question. I am installing a tc lock switch and was wanting to use a lighted switch. I am worried about the B+ for the light backfeeding into the pcm because they would use the same ground when on. Anybody have any experience?

Not exactly what I was looking for, I have my switch hooked up to lock the tc when on, just don't have the 12v hooked up for the indicator led. Switch has three terminals, ground terminal to body, load terminal splices into purple/yellow wire, other terminal is supposed to go to 12v, that's what I don't know if it will cause a problem using the same circuit.

No, it won't cause a problem. The ground on the switch is only for the LED. The only way there could be a problem is if power were connected to the ground connection on the switch, it could back-feed through the light to the load connection. (That is if it were a regular light bulb... An LED is a light-emitting diode, and diodes only let current pass in one direction, so it shouldn't be able to back-feed through an LED even if power was hooked to the ground...)
