Nope the 451M will do just fine.  All you have to do is ground the brown and white wires.  The blue will be your unlock wire and the green will be your lock wire.  The purple wire will go to constant +12V.  If you don't have a dei alarm then the small red will go to +12V( ground if the alarm supplies a +12V output for the locking circuit) and the small blue goes to unlock from the alarm and the small green goes to the lock output.
