The center of the hole must be located 3” down from the top edge and 3” from left side of the lower cover. Using a 3/4” hole saw, drill a 3/4” hole through the steering column lower cover at the pilot hole. Refer to Figure 19.
30) Remove the jam nut from the ROUSH Fog Lamp Switch. Turn the panel over and using flush cut side cutter pliers and the jam nut as a reference, remove portion of the ribbing from around the hole to allow space for the switch jam nut. Debur the hole and install the ROUSH Fog Lamp Switch and jam nut. The switch must be installed with the brass colored terminal to the bottom of the panel. Refer to Figure 20.
31) Route the ROUSH Fog Lamp Harness through the opening in the lower dash. Refer to Figure 21.
32) Return the steering column lower cover to the vehicle. Referring back to Diagram 1, on Page 10, connect the three (3) wiring terminals to the Fog Lamp Switch. Reinstall the steering column lower cover by reversing the removal procedure. Refer back to Step 28. Ensure that the wire harness is not trapped between the lower cover and the dash structure. Refer to Figure 22.
