Hi

I've got a Viper 791xv installed for a year now and just this weekend I added an aftermarket central locking.
I connected the Green and Blue wire of the central locking to the green & blue wire from the alarm system and it wont lock/unlock the doors.
I've tried putting it on negative or positive trigger. I can hear a noise on the central locking unit when I arm the system but it doesnt lock/unlock. The central locking works if you manually push the lock/unlock on the door.

I've only powered the central locking on an external 12v car jumper to test if it works (manual operating of central locking works). It shouldnt make a difference if I connect it to the actual 12v (batt source) and car's earth right?

Do I have to program the remote? it should just unlock/lock when you press those buttons on the remote right?

Hope to hear from you experts soon!

Cheers

Are the green and blue wires definitely the central locking wires? if so test green & blue wire from alarm system for pulses. makes sure doors are closed (or latch door/remove door switch)

"jump/pulse" green or blue wire from central locking with the correct polarity, more than likely a negative. the system should lock or unlock.

If either of these two scenarios dont happen, the system wont work.

also can you replace "green" and "blue" words with their actual use . ie. power unlock/lock. etc. although green and blue is a standard colour for a many central locking systems, other colours can be used.
