I have a 1996 LC with the Factory Running Boards (Black, w/Lockers, 53K miles by the way). The other day I noticed something hanging down from underneath the drivers side running board and went to inspect the situation. There is an aluminium tube approx 1 inch in diameter with two electrical wires towards the rear of the vehicle running down the center of the bottom of the running board. It seems a couple of the plastic retaining clips had broken and the front of the tube was hanging down. I searched my FSM and couldn't find any reference to this part. A trip to the dealer only produced puzzled looks from the techs and parts man who had no idea what this tube was. They gave me some heavy-duty zip ties to secure the part temporarily but no idea how to order the retaining clips or even what the tubing and electrical connection was for. Any ideas?
