That makes more sense. I was thinking one of those solderless types I've seen.This is the harness I used, CTS 500 pots, not a Mustang one.
When I purchased the seller also put the correct tails on for where I could wire the pickups to. This Mustang parts bass was the first/only one I assembled from parts. I'm not a skilled luthier by any means.
