16 Once the Rally-Pac is secured to the steering column, the wire-harness guide channel can be installed. One end of the channel simply slides into place behind the L of the Rally-Pac mounting bracket. The opposite end has to be secured to the steering column with the supplied Phillips head screw. Depending upon the location of the bracket, you might have to lower the steering column to get a drill bit into the right place. If you're uncomfortable drilling into a curved surface, you can always use double-sided foam tape to secure the end of the wire channel.
