08 mustang gt viper 5900 alarm

Car: 2008 Mustang GT without a factory alarm Product: Viper 5900 series alarm with remote start (will not be using remote start) Question: I'm trying to install a Viper 5900 alarm system in my 08 gt and the instructions say to connect the green 14 gauge wire from the satellite relay harness to the key side of the ignition. It doesn't state which wire to tap into. Does anyone know?

It's probably the key side of the cut starter wire. The purple is the starter side of the starter wire.Big Al

So whatever wire I tap into and cut for the ignition wire I then splice in this green keyside starter wire to it?

You are cutting the starter wire...not the ignition wire.. Once cut, you will have the key side of the starter wire, and the starter side. The key side is the side coming from the key cylinder. The starter side, is the other side of the cut wire. Green goes to ignition ( the side going to ignition cylinder)) side of the cut wire. Violet will go to the other side of the cut starter wire.

Thanks guys, I successfully installed the alarm on the Mustang. Only have 1 issue though. When I arm the vehicle my remote beeps twice like it's supposed to, then indicates the door is still open with a third beep even though both doors are closed. Any ideas?

what you used for door triger ? dome light ?

Trigger I used light green and yellow. Dome is the same.

this is possibly your problem. light GREEN/ YELLOW is dome light, you dont want to use this. door trigger is yellow/light green and is positive trigger unlike the negative triggered dome light wire.

Just wired it like you said and it's still doing it
