hi todd,
the front manifold is the same as everyone else has from about your vintage up to the 2000's. only location has changed. the front one uses a HWH RAP1940 solenoid (at over $100 each).
the rear is different than clarkes was. same solenoid valves, but different config. it will be easy to tell what does what. you have someone hit the rear left up leveling switch while in leveling mode and see what solenoid clicks and you can hear air going through. same for down only you will hear the air venting. just do that for up and down on both rear sides. the remaining one is a travel mode. there appears to be another inline solenoid valve that is the small round one that is inline. i need to go look at clarkes again.
so, i would start by tracing them out.
