the wiring diagram is printed right on the back of the 451m. If you are installing a directed unit thered green and blue plug, plug straight into the doorlock output. If you are using another brand the red goes to constant 12v green goes to negative lock and blue goes to negative unlock (from the 451 small ribbon style harness).

door lock-pink / YELLOW- in the dkp

unlock-pink/light green - in the dkp

so off the 451m you will ground the violet/black wire GREEN/ black will go to the lock wire and blue/black will go to the unlock wire

You might not even need to use the 451m unless the pulses from the unit you are installing are not strong enough to power the factory locks.
