“Example part” means any part with the same value and lugs will do; the source does not name a brand. “Generic” stands in for an unspecified pickup: check your own pickup's lead colours before you solder.
Specific to this wiring
- The source says the pickups can be full humbuckers or single-coil-sized humbuckers.
- Red & White wires get soldered together and taped off (on each pickup).
- Each pickup's black lead goes to a common lug on the switch: the neck to the top of one side, the bridge to the bottom of the other. Three short jumpers join four other lugs into one output to the volume.
- The source does not number the switch positions; the lugs are mapped by what they do (neck, both, bridge).
- The green and bare leads of both pickups and the bridge ground wire go to the volume casing; the volume and tone casings are joined by a wire drawn dashed.
- Jack: Sleeve (ground), the inner, circular portion of the jack; Tip (hot output).
Understand this wiring

See the pickup, recognise its two halves, and learn where each coloured wire goes.
Connections
In soldering order: grounds first, then the switch, the pickups and the signal path. Choose Show to highlight a connection in the drawing.

Checked with the Tinkercaster wiring engine against the switching the source describes.
- Hum cancelling and phase describe the generic pickup models, not a measurement of any specific Seymour Duncan model.
- Pickup resistance is not specified, so no numeric meter readings are given.
Before you solder
Ticks are kept in this browser only, as a reminder. They are not a check of your joints. New to soldering? Read the soldering cheat sheet.
Check before plugging in
- In each blade position, the meter across the jack should read the selected humbucker, or both in parallel in the middle.
- The red and white joint on each pickup should not touch ground or any lug.
- With the volume at zero, tip and sleeve should read as a short.
Measure across the output jack with a multimeter on its resistance range. No exact readings are given where the source does not specify the pickups.
