“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
- Sheet legend: 'The standard Ibanez wiring for 2 humbuckers. The 5-way Ibanez HH OEM switch is wired Position 1 = Neck; Position 2 = Neck Parallel; Position 3 = Neck & Bridge; Position 4 = Inside Coils; Position 5 = Bridge.'
- The switch is labelled 'IBANEZ OEM SWITCH' and is drawn from the side with its 8 lugs in a row. The lugs are numbered 1-8 left to right as drawn; lug 4 (to the volume) and lug 8 are the commons.
- Ibanez publishes no contact chart for this switch. Its contacts come from Atheris Pickguards' measured trace map of the opened switch ('Ibanez 3PS1SC5 / COR-TEK 2502N'), which numbers its positions in reverse (its Pos1 = bridge humbucker, Pos5 = neck humbucker). Ibanez's RG2620E factory wiring diagram (RG2620E-CBK-00-02, 2006) wires the 8 lugs with the same roles as this sheet and the map: lug 1 bridge red, lug 2 a neck lead jumpered to lug 7, lug 3 neck red, lug 4 to the volume, lug 5 the bridge series link, lug 6 ground, lug 8 neck black.
- Lug orientation check: with lugs 1-8 read left to right as drawn, the engine reproduces the legend in all five positions. Read in the reverse order, the volume lug would not be a common and the legend fails in every position, so the drawn left-to-right order is the one used.
- The neck pickup is wired with its RED to lug 3, WHITE to lug 2, BLACK to lug 8, and GREEN and BARE to the volume casing. A white jumper joins lug 2 to lug 7.
- The bridge pickup is wired with its RED to lug 1, its BLACK and WHITE together to lug 5, and its GREEN and BARE to the volume casing. Lug 6 is wired to the volume casing.
- The volume's top lug is wired to the volume casing and on to the tone casing, which is drawn to a ground symbol. The tone's signal enters at its middle lug from the volume's bottom (input) lug; the capacitor sits between the tone's bottom lug and the tone casing. The tone's top lug is drawn unconnected.
- The output jack is a 'SWITCHCRAFT® OUTPUT JACK (2-CONDUCTOR) EP1301'. 'TO BRIDGE GROUND' ends on the jack sleeve, which also takes the wire from the tone casing.
- The sheet labels the pickups only 'NECK PICKUP' and 'BRIDGE PICKUP'; a generic DiMarzio-colour four-conductor humbucker stands in for each.

What each position does
| Setting | The source | Engine result |
|---|---|---|
| Position 1: neck | Position 1 = Neck | Neck humbucker (stand-in) (both coils). |
| Position 2: neck parallel | Position 2 = Neck Parallel | Neck humbucker (stand-in) (coils in parallel). |
| Position 3: neck & bridge | Position 3 = Neck & Bridge | Neck humbucker (stand-in) (both coils) and Bridge humbucker (stand-in) (both coils) in parallel. |
| Position 4: inside coils | Position 4 = Inside Coils | Neck humbucker (stand-in) (split to one coil) and Bridge humbucker (stand-in) (split to one coil) in parallel. |
| Position 5: bridge | Position 5 = Bridge | Bridge humbucker (stand-in) (both coils). |
Not simulated: this circuit is drawn for reference only.
- Topology only, because the switch contacts come from a third-party trace map rather than an Ibanez chart (see below). The selector carries the printed legend as selectorByPosition (1 neck, 2 neck parallel, 3 neck and bridge, 4 inside coils, 5 bridge), and the engine matches it in all five positions: 1 neck humbucker; 2 neck coils in parallel; 3 both humbuckers in parallel; 4 one neck coil and one bridge coil in parallel; 5 bridge humbucker.
- The switch contacts come from a third-party measured trace map (Atheris Pickguards, Ibanez 3PS1SC5 / COR-TEK 2502N), cross-checked against the lug roles on Ibanez's RG2620E factory diagram; Ibanez publishes no contact chart.
- Which coil is 'inside' is not modelled: in position 4 the engine keeps the neck's white/green coil and the bridge's red/black coil; the stand-ins do not record which coil sits nearer the other pickup.
- The source's custom-taper pots are not reproduced: both pots use the catalog pot's taper, so settings between the knob ends are approximate.
- Both pickups are generic four-conductor humbuckers; hum and tone describe the generic model, and pickup resistance is not specified, so no numeric meter readings are given.

Check before plugging in
- Position 1: continuity from jack tip to sleeve through the whole neck humbucker only.
- Position 2: the neck's two coils in parallel between tip and sleeve (lower reading than position 1).
- Position 3: both humbuckers in parallel.
- Position 4: one coil of each pickup in parallel.
- Position 5: continuity through the whole bridge humbucker only.
- 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.
