Step 1:

Remove the driver side kick panel to expose the wiring just behind the OBDII connector. Next, locate the BCM, which is found under driver side of the dash to the upper left. Remove the brown BCM connector by pushing the tab inwards and pulling down.

Step 2:

Identify the wires in each pin location on the brown connector. Pin 10, shown here in red, is located 3 rows up and 3 columns from the left. Pin 18, shown here in green, is located 2 rows up and 3 columns over from the right. Wire color may vary between vehicles, therefore, pin locations should be your primary reference.

Step 3:

Utilizing the T-taps provided, attach one to the corresponding wire found in slot 10. Make sure to completely close the T-taps for a proper connection.

Step 4:

Utilizing the T-taps provided, attach one to the corresponding wire found in slot 18. For additional leverage, pliers can be used to close T-taps.

Step 5:

Once both T-taps are installed, find the blue marked end on the module. The marked end needs to be plugged into the wire tapped into pin 10. Proceed to bend the flexible module to connect the other T-tap.

Step 6:

Lastly, reinstall the connector into the BCM. A click sound will be heard confirming the connector has been fully inserted.

Your Installation is now complete!
