Guide # 77191

REV.: 20200407

2019 GMC Yukon – Push Button Start





1) Guide calls out D6 as White/Red.  My T-Harness wire color is Blue/Black.  Is this a problem?


2) Guide says to isolate wires D1 and D3 at the T-Harness connection.  However, these wires terminate at BCM X2 (blue) pin 17.  D1 terminates at the BCM side and D3 terminates at the truck side.  Isolating the T-Harness wires would permanently disable this BCM circuit. Please confirm if the wires require isolating.


3) Guide calls out A3 as Purple/White.  My T-Harness wire color is Purple/Black.  Is this a problem?


4) The Guide says to install a hood pin.  However, there doesn’t seem to be a provision to wire it up to the module.

1- No

2- Just isolate the yellow/blue(d2) and white/blue(d5) wires that should be loose.

3- No

4- Hood/Door pin input is the Pink/Black on the 20 pin connector which should already run into the harness for you.


Thank you for the feedback, I will forward it to our graphics department to have the guide wire colors updated.
