Here is a diagram for that. It is a disc piezo, but they should wire up the same. I have not used a rod piezo yet, so I don't know if you have to be particular when you cut them or not.

On the rod piezo wire after you cut the 1/8" plug off, fish the inner wire [ plastic coated one ] out of the wire braided one [ ground ] the most important thing is you want to get every strand of that braided wire together, twist it up and i apply a light coating of solder to hold it all together. Now with the hot wire i use a bic lighter to melt the plastic coating off the hot wire and apply a light coat of solder to that too. Now it`s ready for connecting to your other componets. Another trick i`ve learned with rods is it`s best to check that it`s working properly all through the stages of getting it ready for the final install into the bridge slot. I do this by having an input with alligator clips soldered on to the tabs, then i can attach it to the rod wires and run it through my cigar box amp and test it to make sure it`s working correctly. Nothing worse then installing a rod in a bridge , stringing up the build and having no sound!!

Thanks, Randy, helps a lot. What are you doing with the braided (ground) wire? Are you leaving it hanging out of the way, or are you grounding it somehow? And using the diagram above, I put the hot wire on the lug shown for the disk piezo, correct? Still not sure what to do with the ground wire. I wired the jack as shown above.

The braided wire from the rod gets soldered on the ground tab on the pot
