“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
- Each pickup's yellow 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 of the other lugs into one output, which runs to the volume's input lug. Two lugs stay empty.
- The source does not number the switch positions; the lugs are mapped by what they do (neck, both, bridge).
- Solder = location for ground (earth) connections. The jack sleeve (ground) is the inner, circular portion of the jack; the tip is the hot output.
Connections
In soldering order: grounds first, then the switch, the pickups and the signal path.

Checked with the Tinkercaster wiring engine against the switching the source describes.
- Pickup resistance is not specified, so no numeric meter readings are given.

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.
