I recently installed a viper 791 on a 1991 Regal 4 door. I was wondering how to unlock just the driver door with the 1st push and all doors with the second. The factory keyless entry does this. I will greatly appreciate any help given. Thanks Wayne |

You will have to go into drivers door I believe and isolate the drivers actuator for drivers priority, other wise I couldn't tell you if there is a wire that does priority access, if anybody out there knows I would like to know too.

Also what you could do is take the driver's panel off(pain in the a** I know) and probe the wires going into the door while pressing your factory keyless, older cars aren't multiplexed, so I don't see why you couldn't find the wire.

Your Viper unit must first be able to do door unlock priority. There needs to be two available outputs to use for unlock. The first one needs to trigger a relay to open the thick tan wire in the driver's kick panel. This wire will show 12 volts + when the door unlock switch is used. The actuator/door side of the cut wire hook to terminal 30; the other side of the cut tan wire to 87a; terminal 87 to 12 volts +. Use your unit to activate the terminals 86 and 85 of the relay coil. Your second unlock output from the Viper hook up to the black wire in the kick panel that shows 12 volts when the unlock switch is used. The first pulse should only activate the driver's door lock motor and the second pulse will activate all the door lock motors.

https://www.crimestopper.com/techweb/InstructionBooks/Alarm/CS2011-15%20Series%20III%20REV%20A%20install.PDF First diagram on Page 13 of 27, But your car has positive doorlocks, so just change the blue and green wire's.
