Hi all
I’m new to guitar modding, and have recently started to mod my jag stang with a new pups.
It had been modded before (not by me) and has a Seymour Duncan JB in the bridge.
I recently bought a hotrails for the neck, and when I had a look inside the guitar, the wiring was very different to any schematics I could find, so I re-wired it following this diagram.

my problem is, both SD pups have 4 wires, I know the red and white get taped together as they are for coil splitting, which I would like to explore in the future, as for the rest I’m unsure and researching it sometimes ends up with contradictory results.
I followed the instructions that came with the HRs and wired up the blacks to switches and the bare and green I took to my volume pot, which has a wire to ground.
This resulted in the JB in the bridge working, but without the oop, but nothing from the HR in the neck……
I followed the advice off an old forum conversation I found who suggested:
“solder the bare wire to ground on the back of one of your pots or wherever else the nearest ground point is.
Solder the green to where the wire labelled black is connected on the diagram.
Solder the black wire to where the wire labeeled white is connected on the diagram” (quote)……
This did not work….
I swapped the green and black wires around because of something else a have read and this gave the result of the pup making a very quiet sound……. Something but not right…..
Could really do with some help here, so thanks in advance
