Hello there. I have decided to swap out both humbuckers on my Fender Jaguar Blacktop. However, I am new to pick-up wiring. I have no problem handling a soldering iron - but I have no clue about the wiring aspect. The setup is two humbuckers, a three-way switch and one volume knob and one tone knob. I have decided to go with a pair of DP103 DiMarzio-pickups.

I understand that this is "standard wiring" and should be fairly simple to do for anyone, but I have zero intuition about this. Any help is greatly appreciated. I do not want to rush into anything before I completly understand the procedure.

So far I have understood this - please correct me if I am wrong:
Each one of the new pickups have four conductors,  two of them are soldered together and one (ground) is soldered to the back of the volume pot. (which seems to be the only action directly involving the pots?). The hot wire is soldered to the selector - basically the same as the earlier arrangement.


This is the current structure:

Where should I start? I will include a couple of pictures. I will supply more if necessary. I have not de-soldered anything yet.
