Can anyone help me I have just finished installing my first alarm (Viper V791) on a 96' pontiac firebird and I am having trouble with getting my doors opened after the door is closed. I have connected the wires like the manual suggests but the remote cannot open my door after they are shut for 2 minutes. I seems that the wire voltage after the door is shut for a period of time. Will I need to have a relay installed to open my doors?
What wire/s did you hook up the unlock wire to? The diagram I'm looking at for your car says you have to 5-wire 2 wires tan and gray black to get the unlock to work properly. So if you didn't do that then yes you will need 2 relays. If you need I can post up the relay wiring.

The unlock blue wire is connected an ORANGE / black wire that is energized only when the doors remain open and will lose power a couple of minutes after I close them. If you don't mind could you post the relay wiring for my vehicle. Thank in advance.
Ok so here it goes. First thing you'll have to do is find the gray/black and tan wires at the bcm in the passenger's kickpanel. When you're testing them, they will rest at ground. Then will pulse to +12v when you unlock the doors. Once you find both of the wires you'll have to cut them in half. Then take 2 spdt relays and wire them up as follows.
Relay #1
85 - Blue unlock wire from the viper
86 - Fused constant +12v
87a - BCM side of tan wire
87 - Fused Constant +12v
30 - Motor side of tan wire
Relay #2
85 - Blue unlock wire from the viper
86 - Fused constant +12v
87a - BCM side of gray/black wire
87 - Fused Constant +12v
30 - Motor side of gray/black wire
As for fuse rating I normally use either a 15 or 20 amp fuse and tie all 4 pins to 1 source. To verify which side of the cut wires is which, the bcm side of the wire will pulse to +12volts when you hit the unlock button. Definately want to make sure you get them the right way around or you could end up causing some serious damage.

My records show that the lock wire is RED / black and the unlock is ORANGE / black at the BCM in the pass kick panel. Both are a negative pulse. You must also pulse the pass door pin before the unlock to wake the BCM up. It goes to sleep after 45 seconds when you lock the doors.

sparkie is right....... i would add use diodes
Sparkie where'd you get that info? Seems a lot easier than the 2 relays I've always used.
