Looking for a wire

I need a wire that comes off my ingition, is "hot" to start the vehicle but goes dormant (if I can use that word...) once she's started. Basically that I could disconnect while running and not disrupt my truck. But if left disconnected and the truck was shut off, it would not restart.

Anyone know of any?

The only wire that does that in the ignition harness its the starter wire itself.

The glow plug relay comes on and goes off after a minute or so when you start the truck as well

That wouldn't stop the truck from starting would it? Might make it harder but assuming its warm it "could" still be started correct

Your looking for a no start switch arent you? That might be a little better to say to explain it although i know your probably worried about security because i read your other thread about security systems. But the one to get what you want done is the neutral safety switch wire(if yours is an automatic) or the clutch safety switch wire(if yours is manual).

Its what prevents you from starting the truck when your truck is in reverse or drive(for auto) or in gear(for manual). As for where they are on the OBS idk for sure but im sure its up under the dash somewhere. Someone else may chime in to let you know

It should be red/light blue. But use a multimeter to find out and be sure.

Exactly correct sir. We have had several rigs stolen lately. I'm looking to put a reed switch in to prevent that from happening. Didn't think about the neutral safety switch. But that's a great thought

On both manual and automatic trucks, there's a four-wire connector down by the brake pedal. On manual trucks, it connects to the clutch switch. On automatic trucks, there's a jumper plug that plugs into the connector, since it uses the neutral switch on the tranny. That would be a convenient place to wire in a kill switch in series.
