“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
- P-Rails pickups use generic-p-rails-four-conductor stand-ins; on-off-on lug map follows the drawn EP1108-style switch.
Understand this wiring
- Seymour Duncan humbucker wire colors
See the pickup, recognise its two halves, and learn where each coloured wire goes.
- Seymour Duncan coil splitting explained
A humbucker has two coils. See how a switch lets you use just one of them.
- Reading Seymour Duncan push/pull switch diagrams
Turning the knob and pulling it do different jobs. See the actual part, then try its switch connections.
Connections
In soldering order: grounds first, then the switch, the pickups and the signal path.

What each position does
| Setting | The source | Engine result |
|---|
Not simulated: this circuit is drawn for reference only.
- The catalog selector model does not reach the output jack on every drawn throw (selectionReachesTip); position labels follow the source sheet, not a verified simulation table.
- The transcribed super-switch map produces a short in the passive model (noShort); lug wiring matches the manufacturer diagram.
- Some switch terminals read as unwired in the catalog contact table (requiredTerminalsWired) despite matching the drawn lug map.
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
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.
