No Unlock wanted
If you want the doors to only automatically lock but NOT to automatically unlock, don’t connect a wire
to the NO contact-D. You will have to manually unlock. Because of the mechanism in CX-9, this requires
to first press unlock on the door before you can open the door with the door handle.
If you would consider this, you don’t need a Relay-A with double contact either, you only need a
SPDT, instead of DPDT. (see Appendix-B shopping list). A tiny bit less cost but a
massive
amount
less comfort. Trust me… you will love automatic unlock once it is installed and wonder how you
could have lived without it.
In case you want unlock sometimes, but not all of the time, you can consider an extra switch on
the dashboard to allow unlock when you want it. (I have not tried this, but I am sure it works)

Unlock only on driver site
If you only want to UNLOCK the door on the driver side when the parking-brake is pressed (on), then do
not connect the grey wire to contact-D, NO. Connect a separate wire to contact-D, NO and the other
side of the wire to White/Black wire on 0940-01E: PIN 5K. This is the connector UNDER the 6 pin
connector on the BCM (see appendix-C). I have not tried this, but I expect this works.
