Hi James, I own a 4000 series, if you still need this info here is the link to the circuit you need. PS-1 (Pre Set- 1) https://www.status-graphite.com/status/frames/index_home.html If this link is a problem the active circuits are in the main menu via online store at Robs main Status site.. You can also click on that link to buy separate pots, the wiring diagrams are in the main menu under information. Hope this helps, Adam
