Starboard side reach your hand above the cup holders, between the speakers and you will feel a cable with 2 nuts and a large washer sandwiched in between. Take two wrenches and unscrew the lower nut, then tighten the upper nut and washer to it, loosen, check, loosen, check, it is trial and error. You can only go so far and the tower will hit the chrome bezel on the speedo. I lowered mine to about a 1/2" over the bezel. It fits in my 7' tall garage attached to the hitch.
