My 4-Way Wiring Colour Codes:

Looking from above with the lead wire exiting the pickup baseplate from the bottom left:

1st coil:
HOT: Green or Yellow
GROUND: Black
POLARITY: South Up

2nd Coil:
GROUND: Red
HOT: White
POLARITY: North Up

if not using the 4-way then its:
GROUND: Black
HOT: RED
... and solder the Yellow/Green wire and White wire together before taping them back with electrical insulation tape.

 

For regular vintage braided wire the outer metal braided sleeve is GROUND and the inner wire core is HOT.

 

If you're using the Seymour Duncan Wiring Diagrams, here are the conversion colour codes:

 

Creamery Green = Duncan Red

Creamery Black = Duncan Green

Creamery Red = Duncan Black

Creamery White = Duncan White

 

Single Coils:

 

White/Cream = Hot

Black = Ground

if there is a seperate Red wire, this is a seperate ground fro the baseplate to ensure 'in-phase' with other manufacturer pickups.
