We've had a lot of requests to sell these. The idea with these pins and sockets was that they would allow people to purchase prewired assemblies that they could install with no soldering required at all. We assumed they would just solve a problem for folks who don't know how to, or who don't care to, solder. But we've found that some players like the idea of having these attached to multiple assemblies, or multiple sets of pickups, allowing them to quickly swap out pickups. Pretty novel idea.
Be sure you understand what you're getting! While the picture above shows a couple of pins soldered onto some wire, with colored heat-shrink tubing, the wire and tubing are not included. The gold-plated pins/sockets are sold loose, and must be soldered by you (they are simply soldered onto the end of a wire). You get one pin and one socket (the image shows two pins).
They fit tight, no need to worry that they'll come apart inside the guitar. Solder them as fits your needs.
