To any of you who may run into a similar problem; I found:
The hot water hoses are connected to an electric valve located outside,above the brake fluid fill/cover. It is connected by wire to the "ford" control panel. (a loose electrical connector at the panel may have been my problem). It may also be connected by vacum hose (blue?) to the "mode" switch. I found the white hose from the mode switch to the vacume electric switch was severly crimpted where Western crammed the hose harness against the firewall. It will be several days before I can give it a smoke test while driving, but parked in the boonies all appears to be working properly. The Vacum schemativ on the aca website was a big help.
