Jacks, HWH 500 series photo?

Would anybody be able to take a photo of a the wiring around the solenoid of a HWH 500 series jack system. Even better, Specifically a 501364 system. The system just does the jacks ,not the slides.
I just bought an 2007 model Rv and somebody has disconnected all the wiring. I need to be able to put it back to its original set-up so I can then chase what ever problem they were trying to bypass.
Many thanks

You sure it's a 500 series? HWH says they were made from 1988 to 1993.

If you scroll down through these it will help you identify your system.

A manual will be your best bet. The valves are so shoe horned in it would be impossible to get a phone/camera in position to take any pictures that would help you.
