## 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).

## What each position does

- Position 1: Neck Pickup (both coils). Source: Engine reading; mini-toggle(s) at rest (throw 1).
- Position 1: Neck Pickup (split to one coil). Source: Engine reading; mini-toggle throws \{"p5":2\}.
- Position 2: Neck Pickup (both coils) and Bridge Pickup (both coils) in parallel. Source: Engine reading; mini-toggle(s) at rest (throw 1).
- Position 2: Neck Pickup (split to one coil) and Bridge Pickup (split to one coil) in parallel. Source: Engine reading; mini-toggle throws \{"p5":2\}.
- Position 3: Bridge Pickup (both coils). Source: Engine reading; mini-toggle(s) at rest (throw 1).
- Position 3: Bridge Pickup (split to one coil). Source: Engine reading; mini-toggle throws \{"p5":2\}.

- Mini-toggle lever states are not independently enumerated; they share the pickup-selector position index.
