## Parts and values

- Bridge humbucker: Bridge humbucker; generic (Humbucker (four-conductor, Seymour Duncan colours))
- Series/split/parallel on-on-on: Series/split/parallel on-on-on; compatible example (DPDT Mini-Toggle (on-on-on))
- Volume 500k: Volume 500k; 500k; compatible example (CTS 500k Audio Pot)
- Output jack: Output jack; compatible example (Switchcraft \#11)
- Bridge ground: Bridge ground; generic (Bridge ground wire)

## Specific to this wiring

- DPDT on-on-on drawn for series (up), split (middle), parallel (down) per source arrows.
- Mini-toggle lug layout mapped to catalog T1–T6; jumper from top-left to middle-right as drawn.

## Connections

1. Bridge humbucker gnd → Series/split/parallel on-on-on T6 (wire, green)
2. Bridge humbucker bare → Volume 500k casing (wire, bare)
3. Series/split/parallel on-on-on T6 → Volume 500k casing (wire, black)
4. Volume 500k lug1 → Volume 500k casing (wire, ground)
5. Output jack sleeve → Volume 500k casing (wire, black)
6. Bridge ground ground → Volume 500k casing (wire, black)
7. Bridge humbucker hot → Series/split/parallel on-on-on T2 (wire, black)
8. Bridge humbucker black → Series/split/parallel on-on-on T4 (wire, white)
9. Bridge humbucker white → Series/split/parallel on-on-on T5 (wire, red)
10. Series/split/parallel on-on-on T1 → Series/split/parallel on-on-on T3 (wire, black)
11. Series/split/parallel on-on-on T4 → Series/split/parallel on-on-on T5 (wire, black)
12. Series/split/parallel on-on-on T2 → Volume 500k lug3 (wire, black)
13. Volume 500k lug2 → Output jack tip (wire, black)

## What each position does

- Toward T1/T4: Bridge humbucker (both coils). Source: Engine reading of the transcribed board.
- Center (bridged): Bridge humbucker (both coils). Source: Engine reading of the transcribed board.
- Toward T3/T6: Bridge humbucker (split to one coil). Source: Engine reading of the transcribed board.

- Standalone mini-toggles use switchPosition; lever states share the selector index unless noted.
