I suspect I’m having trouble with my PATS also - and my 2007 Expy has been stripped down to a roller/camper (removed front end, powertrain, drivetrain, dash, seats, etc) that I plan to tow as a sleeper/camper. I decided to NOT rewire everything, since the fuses/relays in the BJB and SJB give me about 99% (still no SJB power to 5A “radio” fuse #28 for some reason) of what I want (window operation, lights, etc) with just a few jumpers. I hear the internal relays clicking on/off in the SJB which I assume is the PATS going haywire, but not sure how to disable. I may expose the PCB of the SJB and see if I can solder something to kill the annoying clicking sounds.
