Please help! I am a wiring newbie. I am trying to wiring my Gecko 5. I ordered an Aguilar OBP-3 pre-wired ( I assumed this would make it very simple) preamp and am using Nordstrand DC pickups with single/ series /parallel for each. The diagram says attach the bare pickup wires to ground but this usually is sodered to the back of a pot. Where do I attach these grounds since the pickups are attached to switches instead. The Aguilar diagram does no specify, but I am assuming the unattached wire from the jack connects to the bridge ground. Do I try to connect the pickup grounds to th bridge/jack connection or what?
