5706 install can't get the door lock/unlock

So pretty straight forward went from a viper 791vx to the newer 5906v I got every thing working so far except the door locks and unlocks I had them working perfect before and tapped in the same 2 wires on the door lock relay Any help here appreciated

Check your connections. Soldered or ?? Check that the connector is seated properly.When all else fails, Read the Instructions

I would double-check the (-) outputs of the blue and green wires from the 3-pin connector. Double-check with a DMM to make sure it's pulsing (-) out each time you arm/disarm.

The 791 has (had, in your case) (+) and (-) lock trigger outputs. The 5906 is (-) only. Because your locks don't work with the 5906 with no other changes, I suspect your locks are (+) trigger, and you will need to invert the lock output with relays, or use a lock module.

Unplug the 3 pin lock harness from the 5906. Measure the blue and green wires to ground with your VOM. If you see 0-Volts, the car is (+) trigger. If you see voltage (usually 12, but sometimes lower on newer cars) it's (-) trigger. Or post the Model and year of what you're working on, and we can look up the lock system type  instead of guessing.

Thanks didn't know the 791 did +/- The car is a 1996 Chevy Impala SS I am able to connect on the relays for the door locks directly there is a double relay pack I have pulled down from under the dash Thanks for reply

Unplugged door lock harness rests at 0 Positive on lock 12v Negative 12v on unlock

Using ttaps on this nod heat shrinks butt connectors on everything else except the ignition wires I soldered

The lock triggers are POS (+) use a 451 module or a pair of relays.

Oh and throw away the t taps and butt connectors, solder everything after testing.

Ok I have 10 451 modules here I have only used them 2 times before my brain cancer and 400000 seizures my brain is damaged 1 will a 451 serve to work all 4 doors or do I need 2 2 wiring diagram for this 3 thanks if you need I can post from 96 fsm factory wiring diagram 4 can I plug the proximity sensor in the second port on this nrain next to the shock sensor with a dedicated power and ground It took me to long solder all heavy gauges and power these are only 2 ttap the hood trunk tach and only one more butt connector I can't use my right arm and whole right side is in so much pain all the time May I also ask on option for back up battery read a lot of negatives on the viper back up battery I bought I decided not to use
