Clifford Door Lock Question

Hopefully someone will be able to help me out here. I'm installing the Clifford Millenia in a 95 BMW 325i and need guidance on wire connection from alarm module to door lock/unlock leads. The car has a pre-wired alarm connector behind the glove box with most of the needed inputs for plug and play. There is a door lock and unlock wire where I need to tap into however  the Clifford has the following:

RED / Orange - Door unlock (normally open)

RED / Green Door lock (normally open)

WHITE/ Orange Door unlock (common)

WHITE/ Green Door lock (common)

Gray/Green Door lock (normally closed) - not used*

Gray/Orange ( Door unlock (normally closed)  - not used*

*These wires arent needed on my application . Got this info from another BMW owner with same year/model car and a Clifford alarm (cant contact him for this question).

Where do the "common" wires attach to on the car or are they needed? Thanks.
