We have a 1992 Leisure bay that I inherited from my sister. "you move, you keep it". Everything is working except for the hydrojet 1. Hydrojet 2, heater, air, and light all work. I noticed that the control panel has 3 air lines that start at the pump switches and run to the electrical panel in the tub. I found a seperate line coming out of the panel that wasnt connected to anything. I cant see enough of the control panel, or feel it to tell if that line should be pluged into the Hjet 1. From what I can see, it doesnt look like it goes there. I wouldnt think that the line would be tee'd off of another line. I dont have a schematic and was wondering if anyone knows where that line should go?
