I recently purchased a 6 bay SS carwash. I'm wanting to add more options to the bays and seeing if I can do it with the equipment I have. I would like to go with Ginsan meters in the bay, 10 button meters so get get all the function I would like. Don't know if I need to get a new control box to run the functions or if I can modify the one I have. Right now it has, Foam Brush, HP soap, HP Rinse, HP Wax. I would like to add SF Rinse, Tire Cleaner, HP Underbody Rinse and Air dryer.
