Does anybody have the wiring instructions for a DEI-451m..doorlock module?

Answer 1

The 451M module is just two relays build together in one package. If you have a diagram for just about anything using two 12v SPDT relays, you can adapt the 451M to duplicate it if you know the terminal assignments. The color code is usually printed right on the module, but in case it isn't on yours:

Lock relay:
85--small green
86--red (shared with unlock relay)
87--violet/black (combines with violet at fuse holder)
87a--white/black
30--green/black

Unlock relay:
85--small blue
86--red
87--violet
87a--brown/black
30--blue/black

Actual wiring instructions for connecting to factory lock systems will vary depending on what kind of vehicle you're working on.
