Anyone have any luck figuring out one of these Valet systems?

My car has an aftermarket Sony stereo, and I believe the person that installed it messed up the Valet system.

Apparently it was designed to give remote control of the door locks, interior lights, and something else indicated by a AUX button on the remote.

Basically, at this point it's just hanging under the dash and has a couple cut wires.


Also looking for a paint scratch pen that will match the PPE paint code, and maybe a wiring diagram for the car.
