Isolating Backup Light Circuit

Request for a new relay(s) diagram. For Drivers Door Priority unlock, I need a configuration where a momentary (-) pulse from Compustar 800S causes a (+) to be delivered on one circuit at the same time as a momentary(-) is delivered on another circuit. Am thinking that 2 relays will be required. Thanks for your help, Gerald.

Have found the solution to the Drivers priority unlock on 1995 Buick Park Avenue The Factory Remote Accessory Control, sends a (+) to the Unlock Relay under the drivers seat and simultaneously sends a (-) to the Drivers Door Isolation Relay behind dash, passenger side. This causes only the Drivers door to unlock. So a relay is fired with a (-) pulse (Blue) from the Compustar remote, sending a (+) to the White unlock wire at the Unlock Relay under drivers seat, and the (-) pulse from the Compustar is also connected to the Green wire, lower left corner of Door Isolation Relay (locking at rear of Relay Cluster) passenger side Relay Cluster. Like magic only the Drivers Door unlocks. The other doors open on the Second (-) pulse (Orange/Black) from the Compustar to a separate relay sending a (+) pulse to the same White wire at the Unlock Relay under drivers seat as the Drivers priority relay sends the (+) pulse to. The Backup Lights are activated with the Ground While Running wired from Compustar to activate a relay to send (+) to the Gray wire in Drivers kick to the Backup Lights. I also wanted the Heated Mirrors/Rear Defog to operate when remote start is running, so I connect the GWR (-) from the Backup Light relay to the White Wire, lower left corner of 3rd relay from top, left side of Relay Cluster passenger side (looking from rear of Relay Cluster), Heated Mirror/Rear Defog relay. (This factory relay has a Purple wire in the lower right corner, which sends (+) to the Heated Mirrors/Rear Defog circuit.) the GWR wire to the Heated Mirror/Rear Defog relay, requires an inline switch so be deactivated when remote started as desired.(Summertime) Also put an inline switch to the Trunk Release (-) from Compustar, so that it can be deactivated. The remotes work at 1500 feet distance and best not to have the trunk opening by an accidental push of the trunk release, had this happen once.
