ok, basically, i was fixing a pickup on a P-bass style bass, and accidentally broke the wire from the input jack to the pickups, which bit do we re soulder it too?
Ok, so I'm going to assume (in the absence of much info) that you're confused on the pickup lead. Schematic...it's in there somewhere.
Black lead on the volume pot tag; red line on the volume pot case, for earth. IIRC. Might be wrong.
Anyway, there's f-all to get wrong on a P. Dead simple.
