2011 Tiffin Allegro Breeze 28BR Denso dash air

[OurBreeze]

I have an intermittent dash air issue, Sometimes it works just fine, then no power at all to the control panel. I know it must be a loose connection or ground, I have tried to follow the harness, checked the fuses that I have located, but had no luck.
Does anyone have a circuit diagram for 2011 Allegro Breeze dash air?
I have found some on line, but they do not directly apply to my rig.

Thanks in advance.

Visit an auto parts store and look at a "line tracer" or "cable tracker tone generator device", under $20. It uses two leads that attach via clamps and it sends a tone tru the cable that is picked up by the receiver. Handy tool. H

Contacted Tiffin, they were very helpful, culprit was faulty relay. Relay located in driver side electrical compartment. Initial online search for relay was challenging, lot of dead ends as part number did not cross match. Went to auto parts store near me and they were able to quickly find a match.
