Rear window defrost defog 98 jimmy

Does anyone know where I can find the rear window defrost wire for a 98 jimmy, for use with a viper 791xv?

Thanks

Unfortunatly none of my sources list this wire. since I do not have the vehicle in front of me to find it for you i will tell you what I would do. First I would get to the back of the defroster switch to access the wires. I would use my trusty digital multimeter to see what the wires do when I turn the defrost on.  connect the defrost wire of the viper (I believe it's a thin blue on the 791) to a relay and wire it up to send - or + depending on what it needs to the appropriate wire and you are done. Good Luck.
