I also use the same type as does spellcaster (Post No 27) for swapping Strat's entire loaded pickguards easily for testing, modding or upgrading. I have two Strats already equiped with these. The corresponding part connects to what does not need to be remove anymore from the body. I.E the Output jack's two wires and a ground point that takes care of the Bridge/Tremolo claws and the cavity shield. Those pair of connectors came from an RC/Robotic parts supplier but I do not remember which. What telecentric shows on Post No 25 seems to be the same and even having a 4 wire model which was not available when I searched 10 years ago.
