Patriot sprayers ran the switches on the armrest to the boom/speed node. The accuboom then mounted on the boom center mast and the hardwire connection between the switches and boom valves was disconnected and the boom valves ran off the accuboom. Patriot sprayers up to the 40 series is something I worked on for years. I also installed a number of systems on older 3200 and 3150 machines for people. Even a few Patriot II and XL's.

But yeah, if it has a 440 or similar now, the Switchpro just handles everything nicely with an EnvisoPro..
