2016 Cedar Creek Champagne 38el Level-up wiring issue

[Larry and Rebecah]

Hi Folks,
Thanks again for helping me on this project!... The next issue is..
The ICL self leveling system is not working correctly. There's a wire that's not connected and I'm not sure where it goes. I've attached a PDF with some comments to take a look at of you have a little time.

The Level-Up grey wire goes to the front landing gear Hydac solenoid valve. See the attached diagram. Apparently they used your Alta remote unit to shorten/simplify the wiring. My Alta system does not control the landing gear, just the slides/awning/door light.

I note in your picture that the pink wire appears to be partially pulled out of its terminal, or that just may be poor installation, or it may be where the grey wire was pulled from.

The mystery potted black component with the blue and brown wires going to it is probably a full-wave bridge rectifier. They use them as an easy-to-wire blocking diode so normal manual operation does not back-feed the Alta unit. Take it off the wall (square #2 Robertson bit) and look for part numbers on the back side and search for the ID. That's what I did.
