It's not for a Jazz, but will show you the technique to use the terminal blocks. Just x2 for the jazz.

So, which ground wires go with which green wires? Neck pickup ground wire goes with green wire in terminal 3 on neck volume pot, bridge pickup ground wire goes with green wire in terminal 3 on bridge volume pot? What about the bridge ground wire?

What the hell?

Lol what?

The bridge ground would go in number 4 on either terminal block. 4 is shown parallel with 3 according to the little pcb. The P video showed a 3 terminal block with bridge wire connected/twisted with green. The jazz plate just makes it easier to deal with the pesky bridge wire. Also if you have a ground lead from shielded cavity, put that in the other '4' that's empty.

It's what we're all thinking.

Alright, I'll try this! Thanks

Try removing the black qand white wires from terminal 2 on both pots. Keep them twisted together but don't connect them to the pot.

It looks as if the black and white wires have some sort of covering over the ends? Maybe terminal 2 is supposed to provide clamping force to join the wires, but the cover is supposed to keep them isolated form the pot??

Would really help if you posted more pics and maybe the instructions you have.

Did you ever get this working?

FWIW I bought the prewired Dimarzio J kit and followed the instructions exactly with my geddy. The process was esay enough but I had a grounding problem..checked and doublechecked everything and still buzzing. Went back in and realized there is a black wire from the grounding screw (attached to the bottom of the control cavity along with wires from the brass plates and bridge) which was not connected to the pots or jack. I stripped a bit of coating off and attached it to terminal 4 on the bridge volume pot and VOILA...no more noise..Dimarzio did not include that in their instructions but probably should..

A wire from your ground has to connect to the control plate and can easily be screwed into a terminal..done..

Good god, this is pretty straight forward but it's turned into rocket science.

This is an important piece of info for anyone installing a pre-wired Model J set. The instructions make NO MENTION whatsoever of ground wires. It's a glaring omission.
