This is not a question, it's a bug report.

I installed Evo-All + RF411 on INFINITY QX50.

1. Wire color on OBD connector is different : pin 16 +12v - its YELLOW, pin 8 Ign - its White. Unfortunately, I didn't take a photo.

2. After installation, I programmed the bypass and everything worked. LOCK-LOCK-LOCK - and car start.

But after I programmed the RF411 remotes, the car wouldn't start either with the RF411 remote or with the OEM LOCK_LOCK_LOCK remote. There was a transmission error that it was not in park. I reprogrammed the bypass and everything worked.

2014 Infiniti QX50 Extra connections wrong?

Mon, 22 Dec 2014 15:12:40 +0000

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!

PTS access

I have a 2014 Infiniti QX50. I can access all the connectors I need to make except for the PTS connector. I think the only way I can access that is by taking the radio out, but I'm not sure and I cannot figue out how to do that because there are no visible screws anywhere. Can someone who has done one of these please give me some help.

Thanks
