Viper 791vx door lock relay help

[redlinee46s3]

I've installed everything on the alarm but I am having trouble with the door lock relay. It has a three wire pin plug (goes the brain) and a five wire harness. I am having trouble finding which wires connect to the five wire harness.

Relay - DEI 451M

Violet/black (fused) - lock/unlock normally open #87
Green/Black - lock output#30
White/Black - lock normally closed#87a
Blue/Black - unlock output #30
Brown/Black- unlock normall closed#87a

I have tried everything I can think of and can't manage to get to it to work. This relay locks and unlocks the doors when you arm and disarm the alarm.

If anyone can help me locate the wires to hook up to this harness I would appreciate it very much.

I don't think you need the relay if you use the factory lock/unlock control (you can use the 3 wire hookup)... you can also connect it to the master lock/unlock switch in the center console instead of the above locations.

Notes:
*1 When doing remote start, this wire must be isolated from the keyswitch with the ignition relay. *2 The BCM is located just to the right side of the radio. Remove the radio to access. *3 To avoid dome light delay, use red/yellow at the driver door pin for the driver door and red at the passenger door pin for the passenger door. Isolate each door trigger with diodes. Also available @ BCM *4 There are 2 blue/red wires in the ignition harness. The correct ignition wire is the heavier gauge one and it has 1 silver hash mark. The incorrect wire has 2 silver hash marks.

BTW, if you self install a Viper... it voids the warranty.

I've tried without the relay as well. It would lock the car but wouldn't unlock it.I might have had a faulty wire. I will try it again today. Thanks for your help 2way.

I don't really care about the warranty but thanks for the heads up.

PM ASheva10, he just completed the same model install.

I had a faulty wire that is why it didn't work at first. I removed the relay and used the three wires instead.

Good deal:-)
