Here I'm prewiring the electrical harness for Mousa 003. Being a hollowbody without an access panel, the controls all go in through the treble side f hole. To keep everything tidy, I prewire the harness as much as possible on a template. This keeps the leads cleanly routed. I don't want to look in through the f-hole and see a rat's nest (I see shoddy hollowbody wiring all the time - it looks like shit). Now that the harness is ready, I can connect the pickup leads to the mini toggle switches, zip tie the wires and install it into the guitar.
The controls are master volume, master tone (both Bourns sealed 500k pots), Switchcraft 3 way toggle, mini toggle for neck series / split / parallel and another mini toggle for phase selection when both Lollar Imperial humbuckers pickups are on. The tone cap is an Emerson Custom 0.022µf paper in oil. Vintage style cloth wiring ties everything together.
Check out the video below from the daily vlog for the assembly of this harness.
