2014 Infiniti QX50 Extra connections wrong?

0 votes
I installed the Evo, just the T connectors and the PTS wire and it is working Okay. I haven't connected the wires for the door locks or the door pin because there is a conflict.

According to the EVO guide for this vehicle,  A4 and A5 should be connected to the BCM on pin 15 and pin 37 respectively and the door pin A15 to pin 39. I was reluctant to make these connections because according to the Infiniti QX50 service manual http://www.nicoclub.com/FSM/QX50/2014%20QX50/BCS.pdf , pin 15 on the BCM is an output for the ACC indicator lamp; it has nothing to do with door locks. Pin 37 isn't documented in the service manual, but pin 39 is an output for the backdoor antenna; certainly not the door pin. Can you please verify these connections? I want to finish the job, but I don't want to screw up the electronics in this car.

 

Thanks!

The connections shown in the guide are good, I have personally done lots of these cars. Our guide shows the connector WIRE side. In most cases service manual will show connectors from the connector side. A great way to make sure you don't mess with the car electronics is to test before connecting. The lock and unlock are empty pins that you have to insert a wire to work.

 

BTW your link doesn't work so can't really verify.

I could easily breadboard a little circuit that would do what I need to do, I just need to know where to access the trigger in the BCM or whereever it is..or if there is an open collector transistor driving a relay for defrost.
I do not have that info. You might want to check with forums such as http://www.the12volt.com
Thanks! Looks like a good forum, but it doesn't have the info I need.

This may help you

Rear Defroster green - latched dash fuse box, wht 10 pin plg, pin 4 or BCM, grn 40 pin plug, pin 40
Mirror Defroster (same as rear defroster)

Yes, I know where to access the rear defroster. What I want to be able to access is the FRONT defroster. Afterall, I could drive fine with the rear window all frosted up, but I can't with the front window iced up.
