JC uses a double stack for the rotary switch
doors, but they also have
doors with a keypad. At my other wash, I actually have the same exact stand and it was wired for cc and wax, but a few years ago we changed the cc to air dry, so I have no idea how it was wired. I have been calling them every day now for over a week, but of course no answer or call back.
On Ginsan
doors, the control board has rocker switches for motor starter and also for trickle. I'm assuming I would have the motor starter on for the wax/cc, but then still have to have the solenoid kick in for the cc.
