Does you BMW E46 have door lock problem. Check out my web site.

Updated December 29, 2020

Below is a BMW General Module 5 (aka ZKE5 and GM5)
I have gone through the wiring diagrams and compiled this list of connections to the module. Since this module is used in the 3-series sedan, coupe, convertible and wagon as well as the Z4 and X3 there are some differences between the cars which are not listed, but, this list is generally correct. For the most accurate information go to the BMW WDS and look up your specific car.
