EconoHarness 500-3WAY - pre-wired with 3-way switch, 500KOhm Vol & Tone pots + Jack

This is a super-affordable wiring harness for your cigar box guitar or other homemade instrument build, designed for switching between two separate pickups. It includes a standard 3-way switch, slim-profile 500KOhm volume and tone pots (.047uF capacitor on the tone), a standard output jack, and leads. 500KOhm pots are often used with humbucker pickups, but there are no hard-and-fast rules.

The positive leads from your pickup are soldered to the outward facing empty lugs. The unconnected black wire, which is soldered to the casing of the volume pot, connects to both of the negative/ground leads from your pickups. You can run another wire from this connection point if you want to ground to your strings.
