For the EVH Frankenstein pickup's 4-conductor wiring, the Black wire is the hot, the Green and White wires are soldered together and taped off (or used for coil-splitting), and the Red wire is the ground (along with any bare wire). This wiring configuration is for a standard series humbucker connection, but the specific assignment of hot, ground, and coil-split wires can vary by pickup manufacturer, so it's best to confirm with the pickup's specific documentation.
Standard 4-Conductor Wiring (Series Humbucker)
This is the typical way to wire a 4-conductor humbucker, which EVH's Frankenstein pickup likely follows:
Hot: The Black wire is the hot output.
Coil 1 & 2 (Series): The Green and White wires are soldered together and insulated with tape, effectively joining the two coils in series.
Ground: The Red wire is the ground wire, which should be soldered to the back of a potentiometer. If there's a bare wire, it should also be soldered to the ground.
Understanding the Wires
Black: This is typically the signal wire for the pickup's output.
Green: This is the start of one of the pickup's coils.
White: This is the start of the other coil.
Red: This is the end of one of the coils and often serves as the ground connection.
Important Considerations
Pickup Variation: While many manufacturers follow a consistent color code, some variations exist. It is always a good practice to verify the color code with the specific pickup's documentation or to test it with a multimeter.
Coil-Splitting: In some wiring setups, the red and white wires are used for coil-splitting, allowing you to select either coil for a single-coil sound. The "series link" wires (green and white, or red and white depending on the brand) are connected.
Grounding: For proper installation, all ground wires must be securely connected to the guitar's common ground point, often the back of a volume potentiometer.
