If your vehicle has a flow-through console, you may skip some steps.
1. Depress the brake and shift the vehicle into first gear. 2. On each side of the console, remove the black plastic floor trim panel. 3. Remove the center console finish plate using a pry tool and gently prying the top out on both sides. 4. Remove the trim panel surrounding the shifter lever. 5.

1. Remove the two bolts securing the floor console trim in place. 2. Pull up on center console trim to remove, taking care not to damage the alignment tabs. 3. To the left of the radio, locate the skinny panel with the vent and 4×4 selector in it. Gently pull out on the top of the panel and work your way down. 4. On the bottom of the skinny panel, there is a pivot point. Pull the panel out and pivot on this point to allow enough room. 5. Remove the two 7mm bolts securing the pocket in place. 6. Remove the pocket to locate the vehicle brake control harness connector inserted in the back of the pocket. 7. Separate the grey connector from the back of pocket, taking care not to damage the locking tabs.

After removing the center console components as described in Steps 8–11, the vehicle brake control harness connector will be inserted in the back of the pocket.

Take care not to damage the locking tabs when separating the connector.
