Greetings. Im replacing a bridge strat single pickup with a five wire humbucker. If I was running it as a normal humbucker and its was a seymour duncan color coded pickup, the red and white wires would be soldered together but not connected any further to anything. If I want to have it split coiled. One person said, buy a 500k push pull pot, take those two wires, and instead leave them separate and each wire you wire to the two middle lugs on the push pull pot. He then said ground the lug closest to the pot. But, there are two lugs closest to the pot. Do I ground one of them or both. Any help is appreciated. Blessings. Paul wa state.

Just use 2 of the 6 terminals.
Use the 2 that are in the same row, center and "bottom" (close to the pot).
Ground goes to the one close to the pot, the two pickup wires both go to the same one, in the middle.

A 500k pot works well for humbuckers, but it may be a bit too bright for the single coil pickups.

Go ahead and install the 'bucker with the stock electronics and see how you like the sound. If it's not too dark, and particularly if you want to stay as close to original as you can when you split the Duncan's coils, then stick with a 250k value for the volume pot.

Fender use always (?) a 500K where is a humbucker with single coils

With 250 K , humbucker may sound too "dark " . It is also a matter of taste.

I thought there were no coil-split-with-a-push-pull-pot diagrams from Fender (they seem to prefer megaswitches and the S1...), but a little searching brought this:
114-9300-XXX Service Diagram

The wire colors (Fender humbucker vs. the new, non-Fender one) need to be checked.

I have no idea, but at least that diagram is one possible solution. :lol:

BTW, since I'm no wiring guru but want to learn: what's the difference if the push/pull pot is wired as a volume pot (your pic) or a tone pot (the service diagram)?

Interesting way to wire it. Curious how the tone (and noise) is impacted by simply "lifting" the red wire while the green/white is still connected? Seems it would be like hanging an antenna off of the pickup.
