Can we start another place? Does the system function as it is supposed to? If the answer is yes, then I would be reluctant to change any wiring until I fully understood the electrical logic. If the answer is no, then let's figure out the logic before making any conclusions. But, its your coach, put a jumper across to the terminal, and see what happens.

If you put the coach in Level mode, can you raise and lower all four corners?
If you put the coach in Travel mode, does it return to the correct height?
What happens when you press the tag switch?

I am sorry, but as an observer I have not seen any logic to connecting the red wire to the center terminal. Unless you know something that has not come out in the conversation. I do agree something appears to be missing from that terminal. If you look at it carefully, does it show previous signs of a connector scuff mark? But, its your coach, put a jumper across to the terminal, and see what happens.


In one of the pictures a black lead is alligator clipped to a switch, is there any reason for that?

If you want further help figuring this out, then it would help if you took the time and listed each switch, the color and position of the wires exiting. The standard way of designating a wire color with a stripe is the main color is first, followed by the stripe color. Such as White/ blk.
