How to wire those 4 wire humbuckers?

Hello and welcome everybody!

I've searched many sites and forums so far, I tried to understand the wiring and humbucker theory but I can't find the answer to my question. I think for lot of you guys the answer will be simple as you guys know everything about pickups ;) I think it would be a good guide for somebody how to check, measure and wire custom wirings where you need to understand everything not just follow the color codes. Let's get to the point.


Some time ago I decided to rewire and upgrade my luthier guitar. It’s whole mahogany super-strat, 2 humbuckers with 3way toggle switch, 1xVOL, 1xTONE. Simple. Pickups I got were decent but I wanted something more tone flexible so I bought 2 humbuckers with 4 wires each (my previous were 2 wires), decent 3way toggle switch and 2 push-pull pots. Because I can solder a little (did the full wiring for my other guitar with SSH, 1xVOL, 2xTONE + 7way mod) but I lack of theory knowledge, I’ve got a question for you :)

I did some checks with multimeter and here’s what I got:

(-) and (+) refers to the multimeter connection. As you can see the North and South poles are the same way but the sequence (black->green) is opposite. I’m kinda confused. On the drawing the both pickups (as well as coils) are in phase (when I touch the coils and the whole pickup with a screwdriver I got voltage jump to (+) and than when I take it away I got jump to (-)). Originally both pickups were wired green+bare for ground, white+red short and black for hot. In this situation the whole pickup was out-of-phase. I contacted the manufacturer and indeed he made a mistake and clarified that black is ground and green is hot (pickup in phase). The magnets are all hex screws so no slugs and no screws in this one.

If I flip over the bridge humbucker upside down, I got opposite poles (as they should be SN-NS) but the coils sequence will be the same way (12-12). If I flip the wires (green/black) I’ll have the opposite sequence (12-21) but bridge pickup will be out-of-phase to other one.

The diagram I want to solder is this one:

I’m totally lost now which cable is my south start, south finish, north finish and north start. (-) and (+) on multimeter are also confusing because the pickus generate AC current.

Can anybody please explain what is going on here as for a dumb guy in electrophysics like me? How to wire those pickups and which colors will be my SS, SF, NF, NS? How the humbuckers should be wired related to each other?

Many thanks in advance!

You’d want a wiring diagram from whatever brand you are using, then match up the correct colours to the correct parts of the pots. Of you aren’t coil tapping or anything two of the wires will just be tied off

I usually wire neck HB's for spin-a-split, which is much more versatile than coil cut, you get any amount of unbalanced coils you want (unbalanced coils = part HB/part single coil).

Hi guys. Thanks for the replay.

From who, as in what manufacture?

Unfortunately the shop where I bought pickups didn't give me a supplier name (I think some Chinese company), just the color scheme. So that's why I did the check with multimeter.

@Xandeeno Would be great and easy to do :) But I want to understand how the humbuckers relate to each other. You know, like Fox Mulder ;)

@blueman335 That's a great mod, I read about it! I'm planning to wire it in the guitar I'm making now. This will be a SS or HH strat with blender pot instead middle pickup tone control.

Edit: Anyone? Any clue? Any Christmas gift as a reply? ;)
