power door lock switch

Looking to put central power door lock switch in 1993 Range Rover.  OEM alarm utilizes two separate (-) inputs for door lock and unlock.  I want to use a momentary push switch to send both lock (first push) and unlock (second push) negative inputs to OEM alarm.  Ideas and diagrams appreciated.

Oh boy just about the worst vehicle to play with the lock system, it's all CAN data.

Sorry, didn't read the year properly, STILL wouldn't touch it.

what are you tryin to achieve ?

Ted for late 90s and by the way, from the year it could be either a Vogue or "classic" we just gave up on the ECU under the seats and added a slave motor on the drivers door. They are a real PITA. I run a mile from them, late 90s went from British Leyland wiring to BMW then Ford. Even now the Freelander and Disco use a Volvo ignition system so where does our friend start? By the way you will need a custom processor to achieve sequential locking from one switch, a momentary 1 pole 2 way centre off will accomplish this.
