HWH "not in park/brake"

[Jeepinbob]

2004 Alpine Coach FDTS. HWH will not activate due to the "not in park/brake" light coming on. My park brake is set, I already tried turning it on and off repeatedly. I found the HWH specs online and it says to push the reset button. The problem is, I can't find the rest button. I checked the entire battery compartment and the hydraulics panel too, and found nothing.

I tired rebooting all the the power sources, but still nothing. Has anyone had similar problems, and if so, how did you resolve it; or did you find the reset button?

I am grateful for your input, Bob

The parking brake valve has a sensor/relay attached to it that allows the parking brake to talk to the HWH panel. A little hard to see but you can just barely see it. Just reach up there under the dash on the back side of the parking brake valve and feel the 2 wires that are attached to it to see if one is loose. Hope that that is what it is. Easy fix if it is.
