I'll give it my best guess since our coaches are of different vintage. I have at least 2 pressure sensors, one up front on the outside of firewall (as I nderstand, this might be the one you mentioned) and an other one down on the parking brake switch. The light and buzzer should quit at around 90PSI. Our buzzer is behind the gauge cluster just sitting on top of the firewall shelf.

If your aux compressor is from HWH, it is powered directly from the control box through an inline fuse on the power lead right by the compressor. In my case it is a glass fuse in the old style twist holder.

I had travel lite go out and auto leveling light come on and it was caused by a bad momentary switch on the touch pad. Many different problems are caused by the cable connector on back of the touch pad being loose or the other side of the cable at the controller. I had both happen to me. If you have a bad momentary switch on the touchpad, they are easy to replace if you have any sort of soldering skills. I replaced all of them already since some were funky.

I have up and down button on leveling system but only use it to get through obstacles at a croll. Would not use it at speed, could be catastrophic for the ujoints and who knows what else.

Hope some of this will help.
