I am installing the Viper 791 on an 02 Liberty and everything looks pretty straight forward to me except the door lock situation. I have printed all the wiring diagrams from this site but dont understand how what I need to get to make te door locks work all the doors. Could someone please explain to me in laymans terms exactly what I need to do. If someone wants to write up a good step by step for me I would be happy to paypal a little cash for the time spent. Thanks in advance~Brian

You have a one wire system, meaning the lock and unlock are the saem wire. to make you work with your alarm you going to need 2 realys and 2 resistors. For unlock use a 426 ohm and for lock use a 1.4k ohm. can get these at radio shack. As for wireing the relays.
Lock relay
86 12v fused
85 lock output form alarm
30 goes to lock/unlock in car
87 goes to groun

Unlock Relay
86 12v fused
85 unlock output form alarm
30 goes to lock/unlock
97 goes to gound

Put resistors with pin 30 on relays

You have to use realys and resistors. if you have on board relays, look in the manural and compare the pin numbers as above. i dont think the 791 has on board relays, but if it does.

Thanks a lot man. The only other question I have is what relays should I get? I dont believe the 791 has onboard relays either. If you have a paypal account let me know and I will hook you up for taking the time to explain too. Thanks again.

I cant excpet nothign from ya, that waht thsi sight is for. posted_image

but thabks anyways
use a 12volt 30amp automotive relay. radio shack carryes those also but they charge abotu $6 a piece, go to a car auso store ans ask to buy 2 of them see what they charge, you can buy cheaper ones online.
