Locate the BCM as follows

The BODY CONTROL MODULE is under the dash left side above the parking brake pedal area.


To get to it, remove the 10mm bolt that holds the parking brake release lever to the trim.

Remove the 2 philips screws from the bottom.

Remove the left dash fuse block cover.


Ensure the ignition switch is in the OFF position. 

We need connector C1  Light green 27 pins

 and C3 light blue 25 pins.


Both show the end that goes into the BCM so be sure to count the opposite for looking at the back.

Make sure to cut 3-4 inches back from the BODY CONTROL MODULE.


If the enclosure of your NEWROCKIES PRO Module is green and blue, please setup the switches as following (if enclosure is black, please submit a request to our support team for correct switch configurations): 


Open the NEWROCKIES PRO Module's cover (this will NOT void the warranty) by removing the 2 screws on the bottom. Inside there are 2 sets of switches.


Set SW1 (8 switches) as following:

1 2 3 4 5 6 7 8
off off off on on off off on


Leave SW2 (10 switches) the way it is. Close the PRO Module's cover.
