kill switch relay ~ with led indicator light

Have a diagram you're working with?

Guess I'm not really sure how that's wired up, but the route I was thinking isnt going to work if you're interupting a ground. Looks like I'm just spinning ya for a loop without having a diagram. I'm guessing this was the most accessible option found by others, and breaking the positive wire to the injectors might require splicing into the harness at a difficult location.

I could try running my kill switch to a different ground, and see if the injectors still work, as long as that wouldn't hurt anything. If the injectors still work. then the positive side of the wire controls the injectors, and a different positive will be needed for the led light and the switch.

If the injectors don't work with a different ground, then the positive can be used for all three, and the grounds will need to be different, which should probably be the case anyway. In lieu of any warnings, I'll look for a ground and try this, before hooking up the wires to the 5 pin relay.

I'm not sure about this, but as I recall others might not have used the pgm wire because they ended up cutting power to more things than intended

Yes, that was the case, and a .05v loss for each time the switch was used.

I'm using the black/yellow injector wire, from the 10p connector that's under the hood.
