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? Thanks in advance.

 

Still crickets? 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.

 

I can't offer you anything except a subscription.

 

my lighted switch for my gauges is a 2 pole system, it doesn't backfeed.

Grounds a ground though, the whole vehicle shares 1 ground unless its an isolated circuit.

The only other way you could do it would be to make a circuit up that doesn't allow back-feeding at all.
Though, I doubt an LED would do that.
