How to connect Viper Alarm to power locks?
 

I have a 1997 Jeep Grand Cherokee Laredo, 4.0L, 4x4

About three years ago, I had installed a Viper Alarm to my Jeep. The Viper model I had installed was either VIPER 4105V, Viper 350...I don't really remember

However, the Viper alarm only works to active/deactivate the alarm.

The locking/unlocking door feature does not work. Even back then, the factory wireless key entry for locking/unlocking door was not working either.

I remember the tech guy at best buy told me that I had to buy a device, but I never followed.

Anyway, recently I thought that this would be a nice feature to have...but how would I get started to make this happen?

Get the installer manual and buy the part

Adding the lock feature
 

If you get me the model number of your viper alarm I can look up which wires to hook to what to have it work the door locks.

Part | Wire Color in Car | Location in car.
POWER LOCK | ORANGE/VIOLET and PINK/BLACK (TYPE C) See NOTE *2 | IN BOTH FRONT DOORS, See DIAGRAM

POWER UNLOCK | PINK/BLACK (TYPE C) See NOTE *2 | IN BOTH FRONT DOORS, See DIAGRAM

NOTE *2 Use ORANGE/VIOLET for LOCK and PINK/BLACK for UNLOCK at the DRIVERS DOOR SWITCH. Use BLACK/WHITE for LOCK and PINK/BLACK for UNLOCK at the passenger front door switch. This vehicle requires (2) of part # 778 one for each door See DIAGRAM.
