I was surprised to find a 'quick connect' plug inside my Fender Ultra Strat connecting the pickguard harness with the ground/trem claw and output jack. How long has Fender been using these plugs in their guitars? Where could I find a matching male plug to install in a new loaded pickguard for quick pickguard/pickup swaps? Are there any resources that address these 'quick connect' plugs? I've found some forum threads talking about DIY plugs like this but nowhere discussing these specifically used by Fender in strats. For reference, you can see it in the Ultra HSS specs doc here, item #34 on pg. 3 and in the wiring diagram on pg. 4. Also attached the PDF doc. Any insights are greatly appreciated. Thanks!
