Thanks in advance for any help! I recently refinished and switched out the pickups of my ‘80 SG Firebrand. Pickups are Fralin P-92’s. The bridge is a 3-wire lead, the neck is a braided single wire. The issue is... the only way I get sound is to touch the neck pickup and the 3-way switchcraft jack. I have zero clue how to start thinking about this.. here’s a photo. Any help would be great! Thank you.
