“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
- Title: 2 SINGLE COILS | 1 HUMBUCKER | 1 VOLUME | 2 TONE | 5 WAY BLADE Auto-Split.
- The blade is drawn at an angle. On its upper row the four lugs carry, from the top: the humbucker black, the middle white, the neck white, and a white that loops under the blade to the volume (the row's common).
- On the other row the humbucker's red and white go together to the second lug from the top; the lug below it has a black to the upper tone's Solder spot; the top and bottom lugs are drawn empty.
- The neck and middle whites each loop over the top of the blade before landing on their lugs; the neck white curls once and the middle-tone wire passes under that curl without joining it.
- The humbucker's green and bare, and the neck and middle blacks, go to the volume's Solder spot, which also takes the wire to the jack sleeve and a wire to the upper tone's Solder spot.
- The volume's third lug is bent onto the casing under the Solder spot.
- Upper (neck) tone: a white from the blade's neck lug goes to its middle lug; the lug next to the lower tone carries the .047 cap to its Solder spot and a short white to the lower tone's middle lug; its remaining lug is drawn with an empty eyelet.
- Lower (middle) tone: a white from the blade's middle-pickup lug goes to the lug nearest the upper tone; its middle lug takes the short white from the upper tone's cap lug, so both tones share the one cap; its remaining lug is drawn with an empty eyelet. Its Solder spot takes the Bridge ground wire and a wire from the upper tone's Solder spot.
- The source does not number the blade's lugs or positions; the lugs are mapped by what they do. The second row is read from its common, the lug diagonally opposite the first row's common (see the terminal mapping).
- Legend: Solder = location for ground (earth) connections. Jack: Tip (hot output); Sleeve (ground). The inner, circular portion of the jack.
- The only value printed is '.047 cap'; no pot values are printed.

A humbucker has two coils. See how a switch lets you use just one of them.

What each position does
| Setting | The source | Engine result |
|---|---|---|
| Position 1: bridge humbucker | Humbucker black on the upper row's top lug; the floating second common touches only the red & white lug, so nothing is grounded. | Bridge humbucker (both coils). |
| Position 2: bridge split + middle | Auto-split: the second row's wiper bridges the red & white lug to the grounded lug. | Middle single coil and Bridge humbucker (split to one coil) in parallel. |
| Position 3: middle | — | Middle single coil. |
| Position 4: middle + neck | — | Neck single coil and Middle single coil in parallel. |
| Position 5: neck | — | Neck single coil. |
Not simulated: this circuit is drawn for reference only.
- The sheet prints no pot values; 250k stand-ins are used.
- The blade's lugs are unlabelled and mapped by function. The second row is read from its common, the empty lug diagonally opposite the first row's common: T8, then T7 (positions 1-2), T5 (2-4), T6 (4-5).
- The second pole's common is drawn empty: it floats and only bridges its own throws, so in position 2 it joins the humbucker's red & white to the grounded lug.
- Both tones share the one .047 cap: the lower tone's middle lug is wired to the upper tone's cap lug. The engine names only the upper (neck) tone in positions 4 and 5 and does not model the middle tone's route through the shared cap.
- Each tone is wired between its signal lug and the cap lug, so it works as a variable resistor in series with the cap; it is modelled as drawn.
- Hum cancelling and phase describe the generic pickup models, not a measurement of any specific Seymour Duncan model.
- Pickup resistance is not specified, so no numeric meter readings are given.

Check before plugging in
- Position 1: tip to sleeve reads the full bridge humbucker.
- Position 2: the humbucker's red & white read ground, and the reading drops to one bridge coil in parallel with the middle.
- Positions 3 to 5: the bridge humbucker is out of circuit.
- With the volume at zero, tip and sleeve read as a short in every position.
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.
