Ok i have an essex jazz bass and i just got a pair of MEC p/u with one wire coming out of each. The essex p/us that are being replaced have two a white and a black on the front or a white and red on the back. I have no idea what i should do. Both of these are very thin but the ones coming out of the MEC are real thick. I was thinking of just undoing the other wiring and wiring from pot to pot and taking the mecs and soldering them right onto the pots. How do you think i should wire them? Also there was a stray wire wired to a pot going to the bridge.(the actual bridge not the pickup) Does that have any purpose or is that just a mess up?
