My HWH Hyd Sys

Just bought this coach a few months ago. Didn't get much documentation with the coach. Trying to learn the hydraulic system.

I would like to know what HWH series I have for Room Leveling. I notice different bands on wiring going to solenoids, orange, green, blue, brown. Would like to know what slides the solenoids serve.
Also the red, orange, blue markings on the fwd side of the manifold.

What slideout manual number do I need to obtain to identify these markings?

I don't know anything about your specific coach, but you can find the manual at the following link.

Regarding your leveling system, I have found that the HWH web site is a good resource.

More than likely you only have one slide that is hydraulic, two at the most. You will have one solenoid for each of the four levelers and two for each hydraulic slide. Your bedroom slides should be Schwintek in wall gear driven.
