I have a 2004 Grand Prix that I'm installing a Viper 791xv in and I have a couple of questions.

1.  Does anybody know what wire I would tap into for the rear defroster?  Also, is it latched, pulsed, etc?

2.  Do I need to hook up the factory arm/disarm wires.  If I do hook them up, will I that allow me to retain some of the factory keyless entry features such as illuminated entry even though I'm using the Viper alarm?

3.  I can turn the factory anti-theft off in the information display in the car.  Should I turn it off since I'm using the Viper, or leave it on?

4.  I noticed the the ignition cylinder has a plastic ring around it.  Do I just put the antenna ring from the 555U bypass module around it, or do I have to get it behind the plastic ring and around the actual ignition cylinder?  Also, the antenna ring is much bigger than the cylinder.  Do I just use some tape to keep it on?

5.  Finally, do I need to use relays for the door locks, or are they a low enough draw that I don't need them?

Thanks

To clarify #2, by illuminated entry, I mean exterior lights, not the interior.  I know I can turn the interior lights on with the Viper.  My car will turn the foglights and reverse lights on when it is dark out and I disarm/unlock the car with the remote for the factory keyless entry/anti-theft.  I was wondering if I hook up the factory disarm wire if I would be able to retain this feature and when disarming the Viper, my lights would still come on when its dark?
