Specific to this wiring
- Title: 1 SINGLE COIL SIZED HUMBUCKER | 1 SINGLE COIL 1 SINGLE COIL SIZED HUMBUCKER | 1 VOLUME | 2 TONE | 5 WAY BLADE Auto-Split.
- The neck and bridge pickups are drawn as Seymour Duncan Research boards (pads Finish, R, W, Gnd, B, G, Start); their leads leave in a cable of black, red, white, green and bare.
- Neck, middle and bridge hot leads (neck black, middle white, bridge black) go to three lugs in one row of the blade; that row's bottom lug is the common and its white loops round under the blade to the volume's first lug.
- On the blade's other row the top lug is empty. The bridge red & white go together to the lug next to it, a black runs from the third lug to the volume's Solder spot, and the neck red & white go together to the bottom lug; the neck pair carries the hop where the two pairs cross.
- Neck and bridge green and bare, and the middle black, go to the Solder spot on the volume casing, which also takes the ground wire to the bridge and the wire to the jack sleeve.
- The volume's outer lug is bent onto the casing under the Solder spot.
- A second black from the neck lug runs to the upper tone's middle lug; a black from the middle lug runs to the lower tone's outer lug. The lower tone's middle lug is jumpered to the upper tone's outer lug, which carries the .047 cap to the upper tone casing.
- The two tone Solder spots are wired together, and the upper tone's Solder spot is wired to the volume's.
- The source does not number the blade's lugs or positions; the lugs are mapped by what they do (bridge, bridge + middle, middle, middle + neck, neck). The second row is mapped so that the title's auto-split holds (see the terminal mapping and limits).
- Legend: the grey Solder spot marks the location for ground (earth) connections. Jack: Tip (hot output); Sleeve (ground). The inner, circular portion of the jack.
- The tone cap is printed '.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 | Bridge black on the wired row's top lug; the bridge red & white lug is bridged to nothing that is grounded. | Bridge single-coil-sized humbucker (both coils). |
| Position 2: bridge split + middle | The floating second-pole common joins the bridge red & white lug to the grounded lug: the auto-split. | Middle single coil and Bridge single-coil-sized humbucker (split to one coil) in parallel. |
| Position 3: middle | Middle white only; the grounded lug touches neither red & white lug. | Middle single coil. |
| Position 4: middle + neck split | The floating second-pole common joins the neck red & white lug to the grounded lug: the auto-split. | Neck single-coil-sized humbucker (split to one coil) and Middle single coil in parallel. |
| Position 5: neck humbucker | Neck black only; the neck red & white lug is not grounded. | Neck single-coil-sized humbucker (both coils). |
Not simulated: this circuit is drawn for reference only.
- The sheet prints no pot values; 250k stand-ins are used.
- The blade's second-pole lugs are unlabelled and mapped by function: the reading that reproduces the 'Auto-Split' title (the lug next to that pole's empty common is live in positions 1-2, the bottom lug in positions 4-5), matching the published Strat Stack Plus/SCH five-way sheet and the lug order DiMarzio prints for its five-way (EP1104). Read the other way round (as in the blocked 1SCH_1S_1SCH_5W_1V_AS draft), the grounded lug would only meet the humbucker that is switched off, and nothing would split.
- The second pole's common is drawn empty: it floats and only bridges its own throws, so in positions 2 and 4 it joins one humbucker's red & white to the grounded lug.
- The lower tone reaches the .047 cap only through the upper tone's track (shared cap), so the engine names only the upper tone (positions 4-5); the lower tone on the middle throw (positions 2-4) is not reported.
- The single-coil-sized humbuckers are modelled by a generic four-conductor humbucker; hum cancelling and phase describe the generic models.
- 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 bridge red & white read ground, and the reading drops to one bridge coil in parallel with the middle.
- Position 4: the neck red & white read ground, and the reading drops to one neck coil in parallel with the middle.
- Position 5: tip to sleeve reads the full neck humbucker.
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.
