Instrument gauges

[wratchet]

I have an 06 4076 tuscsny dp.
While connecting to the trailer brake conrol harness, key on, nr.
The dash acted as though I had just turned key on. Like everything shut down & restarted.
Fuel, alt, gauges work fine.
Air pressure, oil pressure gauges now dont function.
Low air buzzer works.
Anyone ran into this?

Dang, I sure hoped somebody else had these problems. My front air shows low pressure and that annoying buzzer won't go off. When I turn on the headlight switch suddenly my rear air drops to zero. BUT I still have air as my suspension and brakes work. I have the Escaper 39-49 ft with 350 Cummins, 2001 model. Have you figured out your problem yet?
