I'm sitting here trying to install some DiMarzio DP123's in my MIJ Jazz. I'm confused. There are 4 wires from each p/u, red, green, black, and white. The instructions say to solder red to leg 2 of the respective pot, and solder green to the back of the respective pot. No problems. The black & white wires are apparently for use with a series/parallel or phase switch, which I don't have. So the instructions say to (quote) "solder the black & white wire of each pickup together". Does this mean solder black & white of p/u #1 together, then solder black & white for #2 in a SEPERATE connection? Or, does it mean to solder black to black, and white to white? Thirdly, if you read it long enough, it starts to sound like you solder all four together! I know lots of you guys recommend this p/u; any of you do the work yourself? BTW, I checked their website, and their instruction there is an identical copy to what I have here, no diagrams. Thanks!
