door lock/unlock relays for viper alarms

in the installation guide for vipers...it says that the green and blue door lock/unlock wires should be used ONLY to activate realys but i was told that you can connect them directly to the car's unlock/lock wires WITHOUT using relays...is this true?   i was taught to always use relayts but if you dont have to then that would be easier...someone please help!!!    do you have to use relays or not?Derek

Depends on the car.Certified Security Specialist

Always check info with a digital multimeter.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

so basically i can hook up the unlock/lock wires to the cars wires and if it doesnt work then i know to use a relay?Derek

NO. You find out what type of locking system the vehicle has then you hook it up the correct way. If you just hook the wires up without verifying the type of locking system you run the chance of destroying the car's computer or the alarm.Certified Security Specialist
