Infiniti M37 Wiring Diagram Error?

0 votes
I am preparing to install a EVO-NIST1 (with T Harness) on a 2012 Infiniti M37 and have a question concerning the proper pin positions on the Driver Door Connector for the (-)Unlock and (-)Lock signals.

Your instalation guides provide conflicting information for the (-)Unlock and (-)Lock signals.

For the Driver Door Connector your guides list Pin 14 (green) for (-)Unlock and Pin15 (Red) for Lock.  The diagram of the connector next to this description highlights pins 15 and 16 however.

The Wire Color pictures for the M37 show a similar looking connector but put the red wire in the position that would be Pin 15 (but they call it pin 109) all but the pin number agrees with your guide.

However the wire color picture shows a Green (-)Unlock wire going to the position that would be pin 16 (they lable it as pin 111).  This differs from the pin 14 listed in your guide.

I found another wiring diagram for the M37 that is somewhat unclear but makes it appear that (-)Unlock should be pin 16 and (-)Lock should be pin 15.

What are the correct connector pin positions for the (-)Unlock and (-)Lock signals?

It is a 2012 Infiniti M37
This is the information I have for the lockw ires in your vehicle.

Lock.Arm: Red - Negative (-): At power window main switch...(so inside the door) 16 pin plug, Pin 15.

Unlock/Disarm - Negative double pulse (-): At power window main switch...(so inside the door) 16 pin plug, Pin 16.

Tell me if this matches your vehicle.
