My pickups aren't here yet, but I just want to make sure I have it right beforehand.
Here's the JP7 wiring diagram:
And here's BKP's wiring diagram. This is for a 5-way, but they don't have a 2H/1Vol/1Ton schematic up for H-H. I have 4-conductor pickups.
Here's the inside of (someone else's) JP7:
As I understand it then, the green and red on each should go to the (tiny...) connectors on the circuit board (back of the switch), and the black/silver get connected and run to ground? Or am I way off?
Nah fucker, all of them connect to the circuit board on that, you just need to translate the wiring code.
