The wiring and solenoid kit is available from PATC for the 46RH. They do not make one for a 42RH.

Not arguing, but seems hard to believe they 46RH controller wouldn't work on a 42RH. The plug is the same, they function the same, one is just more HD. But I'm no expert, so maybe I am missing something.
