Jeffery is RIGHT! Wire size does matter! If you use the Cruise Control wires as part of the Starter system, every time you use it, you'll be buying a new Cruise Control Switch (Which isn't cheap, since it'* part of the MULTIFUNCTION SWITCH: Turn Signals, WSW Switch & Cruise Control Switch)! So do really want to spend $300 - $400 EVERY time you start the car?????? A seperate "Dedicated" switch is the ONLY way to go! It'* cheap, hidden & best of all won't cost you that much!

Back in the late '70'*, I ran the little starter wire on my '64 GTO through a very tiny sliding microswitch.
The switch was superglued to the back side of the steering-column bracket and the sliding part of the switch faced out through a little hole in the bracket. You could get under the dashboard and LOOK right at the little slide and never know it was a switch. It was easy to reach, as long as one knew the exact location.
The little switch worked like a champ for the next 13 years.
Two ex-wives never figured out where the thing was hidden, either. Heh, heh, heh...

I've done this to every car I've owned in the last 10 years:

Wire a remotely fused switch into whatever circuit controls the fuel pump. Why? If someone gets in, and it won't crank, they LOOK FOR A SWITCH! If the car cranks, but won't start, they think it'* a broken POS.

I didn't do this to my Bonneville, because they need my key, or need to be a real pro to be prepared for VATS or Passkey, and on top of all that, I have the full factory security system.

If you're gonna do it anyway, try that trick. There'* also a fuel pump pin on the ALDL connector.....not sure how it'* used, but it can be figured out.

I'll tell you that trick actually worked on her Suburban before our divorce, too. Fooled her a couple times, even though she knew it was there.

95% of the car thieves out there will give up if the car cranks, but doesn't start. No crank, and they're looking for a device. They'll do damage, but they won't get the car.

I wish i knew how to wire it up to a switch and everything

Dillon, it'* really easy. You can buy the auxiliary fuse holder with 2 wires coming from it at an auto parts store for a couple bucks. You just put two terminals on the wire ends so it'll plug in where the original switch was. Then move the fuse into it. Pick one of the 2 wires, and cut it. Install the switch in between.

Cake.

Instead of all of this wiring of a security system, i got a better idea. it'* called ejector-seats. I think that'd get a really good look outta the car theif as he is flying sky high. Just a suggestion. could it work? LOL j/k
