Chevy S-10 Wire

The alarm sends a ground thru the orange wire whenever it's armed and the red wire on the relay needs to see 12volts during crank to activate the relay. It can accomplish this on either the pink igntion wire or the yellow starter wire so both should do the job. To check your install simply arm and trigger the alarm then try to start the truck with the key. If it won't crank over it's working....Mike M2

yeah you should use the start wire for your 12volt activation on the starter kill relay....not an ignition wire.....some starter kill wires are diode isolated but you can still get a trickle effect through the relay.....got atech bulletin from gm stating that ignition powered starter kill relays can cause early failure in catalytic converters because of  a milliseconds worth of  droop out on the relay causing  the ignition circuit to temporarily shut off while the vehicle is running.......yes yes i know its just gm's way of getting out of warranty work.....but your better off just not doing it and covering your anus....

NO, you should have two hooked to the same wire. You should be cutting that yellow start wire to start with and feeding it thru the relay, just as they show in the diagram. Attach the red wire to the end of the start wire that is coming from the key. Like Snottdobs, i always do it this way on Avox alarms. Other brands like DEI wire thier relays with the #30 position going to ignition. Both will work, but i do prefer the starter wire...Mike M2

The proper method is to use the ignition wire in the harness to supply power to the starter kill relay. Using the starter wire may work most times, but I have had a few instances when it won't work quickly enough and the car can start. Snotdobbs. The bulletin you are refering to isn't about starter kill relays. It is about ignition kill relays. GM has noted, that over time the contacts within a relay that is used for an ignition kill can momentarily open with vibration while driving. This will briefly cut power to all vital ignition systems. As a result, at times fuel is pushed through the engine and not combusted fully. This in turns leads to a build up in the catalytic converter and shortens its life span. Honda has also issued such bulletins to their dealers. sparky
