I have an SX jazz and an SX p/j. I got an MIA fender jazz pups/controls setup from a TBer. So far ive taken out the SX stock stuff. Im going to shield the cavities and then install the fender stuff. There are a couple of round lugs soldered into the fender wiring. what are these for? I think ill have to cut them out of the wiring to make it fit through the channels unless theres a reason they are there? They are on the black leads from from the bridge pup an a black wire coming from the neck volume pot. Also, eventually I will put Dimarzio DP126 in my sx p/j. I have a stock wiring harness from a MIM fender jazz. Can I just disconnect the pups and use the MIM electronics with the dimarzios, even though they will be P/J? Is MIM pots teh same as MIA fender? All say CTS... Thanks!
