HELP: Warwick MEC pickups + Seymour Duncan STC-2A

Long story short, I took my Warwick Streamer apart literally years ago to refinish it, which I just got around to finishing... I'm going to put everything back together and I realized I never took a photograph of what the wiring looked like beforehand and the wiring diagram from Seymour Duncan doesn't have all the information I need.




I think I got everything wired correctly except for the pickups. I'm not exactly sure how to handle them, all the pickups I've delt with in the past had two wires, the Warwick MEC pickups have 5 each split into two groups.

Group 1: (white + green wires) I assumed this was the "hot output" and have them both connected to the middle pot in the wiring diagram.

Group 2: (red + black + unsleeved) I don't have a clue what to do here. I'm guessing this should be the ground wire, but I'm not sure where to put it. If you look at the pic below, there really isn't much room slack so it must have been connected someplace around that middle pot...




Any help would be much appreciated.

Thank you!


EDIT: So i ended up soldering all those wires to the selector potentiaometer casing. I'm now running into an issue where the volume knob isn't working, it seems like the volume is stuck wide open, however I'm not 100% sure because I don't have strings attached.

 

so I just soldered on both the "ground" wires to side of the middle pot. Everything is work, but it seems as though the volume is stuck on, also I'm not sure if the active/passive switch is working. I'm just tapping a screw driver against the pickups as my test...

 

The pickups are soap bars. Your assessment makes sense. I soldered everything to the pot case (it's a little messy, but it's done properly).


I got the multi-meter in, I'm going to try to figure out how to do continuity tests and see if there's any break in the ground connection.
