“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
- Mini-toggle tags mapped by function from the catalog contact table where the source leaves them unlabelled.
- The engine steps the pickup selector; standalone mini-toggles share that position index (modifier contacts close when the index matches).
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 |
|---|---|---|
| Position 1 | Engine reading; mini-toggle(s) at rest (throw 1). | Neck Pickup (both coils). |
| Position 1 | Engine reading; mini-toggle throws {"p5":2}. | Neck Pickup (split to one coil). |
| Position 2 | Engine reading; mini-toggle(s) at rest (throw 1). | Neck Pickup (both coils) and Bridge Pickup (both coils) in parallel. |
| Position 2 | Engine reading; mini-toggle throws {"p5":2}. | Neck Pickup (split to one coil) and Bridge Pickup (split to one coil) in parallel. |
| Position 3 | Engine reading; mini-toggle(s) at rest (throw 1). | Bridge Pickup (both coils). |
| Position 3 | Engine reading; mini-toggle throws {"p5":2}. | Bridge Pickup (split to one coil). |
Checked with the Tinkercaster wiring engine against the switching the source describes.
- Mini-toggle lever states are not independently enumerated; they share the pickup-selector position index.
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.
