I'm reading about so many having difficulty installing the unit. The nut and pedal being a problem. STOP. You don't need anything more than a Phillips head screw driver. Remove two screws and you are done in 5 minutes.
First remove the screw on the side of the console where the vent is. After that is removed remove the second Phillips screw holding the side panel on the console in place. Remove the drivers side of the console. Now look back above the gas pedal and there is the plug. Squeeze the sides to release the locking mechanism on the plug. Unplug and insert the SB. Replug the plugs with the SB in line. Replace console side and screw and then the vent and screw and now you are done! No pedal removal or nut to drive you nuts. Simple.
