“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
- 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).
Understand this wiring
- Seymour Duncan humbucker wire colors
See the pickup, recognise its two halves, and learn where each coloured wire goes.
- Seymour Duncan coil splitting explained
A humbucker has two coils. See how a switch lets you use just one of them.
- Reading Seymour Duncan push/pull switch diagrams
Turning the knob and pulling it do different jobs. See the actual part, then try its switch connections.
Connections
In soldering order: grounds first, then the switch, the pickups and the signal path.
| # | From | To | How |
|---|---|---|---|
| 1 | Mini-toggle bottom-left lug (T3) to volume casing (ground for split) | w3 | Wireblack |
| 2 | Pickup green to volume casing | w4 | Wiregreen |
| 3 | Pickup bare to volume casing | w5 | Wirebare |
| 4 | Volume right lug (lug1) bent to casing | w7 | Wireground |
| 5 | Jack sleeve to volume casing | w9 | Wireblack |
| 6 | Bridge ground wire to volume casing | w10 | Wireblack |
| 7 | Pickup white (red lead) to mini-toggle middle-left lug (T2) | w1 | Wirewhite |
| 8 | Pickup red (white lead code) to same mini-toggle middle-left lug (T2) | w2 | Wirered |
| 9 | Pickup black (hot) to volume left lug (lug3) | w6 | Wireblack |
| 10 | Volume middle lug to jack tip | w8 | Wireblack |
What each position does
| Setting | The source | Engine result |
|---|---|---|
| Toward T1 | Engine reading with the pickup selector stepped; mini-toggles share that position index. | Bridge humbucker (both coils). |
| Toward T3 | Engine reading with the pickup selector stepped; mini-toggles share that position index. | Bridge humbucker (split to one coil). |
Checked with the Tinkercaster wiring engine against the switching the source describes.
- Mini-toggle lever states are not independently enumerated; they share the pickup-selector position index.
Before you solder
Ticks are kept in this browser only, as a reminder. They are not a check of your joints. New to soldering? Read the soldering cheat sheet.
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.
