Wiring
Pick the voicing you're building and you'll get its bench-side wiring reference: the selector map, connection points, and the published harness.
This is the bench-side reference for the Relay Torch harness. It gives you the selector map, pickup roles, labeled connection points, and the published base wiring without trying to turn the page into a full soldering class.
Control Layout
5-Way Blade
Bridge
Bridge humbucker alone.
Bridge + Middle
Bridge humbucker and Mean 90 in parallel.
Middle
Mean 90 alone. This is the main Torch destination.
Neck + Middle
Neck humbucker and Mean 90 in parallel.
Neck
Neck humbucker alone.
Volume - Standard 500k audio taper.
Tone (push-pull) - The published base harness uses the pot as a standard tone control. The push-pull switch lugs stay open until the Torch edge contour is finalized.
Pickup Layout
- Bridge:
GFS VEH Humbucker, bridge cavity, strongest driven voice. - Middle:
GFS Mean 90, middle cavity, main Torch voice. - Neck:
GFS Professional Series Alnico II Humbucker, neck cavity, rounded supporting voice.

Leave TON-A1 through TON-B3 open in this published revision. Those six switch lugs are reserved for the Torch edge contour and are intentionally unused in the base harness.
Build Outline
Outline
Shield the cavity first
Torch puts strong midrange right at the center of the selector map, so keep the control cavity quiet before any hardware goes in.
Build the base 5-way harness on the bench
Wire all three pickups to the selector, then complete the volume, standard tone branch, and output jack before you think about installation.
Keep the ground scheme simple
Use one ground bus for shielding, pickup returns, pot backs, capacitor ground, and jack sleeve.
Install only after the selector map is proven
Verify the 5-way positions and tap-test response before the harness goes into the body.
Sanity Checks
Checks
Continuity
In each selector position,
SW-OUTshould connect only to the expected pickup lug or lugs. Position 3 should isolate the Mean 90.Resistance
With volume full up, measure between
J-TIPandJ-SLV. Expect roughly 11.2 kOhm in position 1, 8.7 kOhm in position 3, and 7.6 kOhm in position 5, with positions 2 and 4 reading lower because the pickups are in parallel.Tap test
Plug into an amp at low volume and tap each pickup with a metal screwdriver. Make sure the Mean 90 is isolated in position 3 and blended only in positions 2 and 4.
