So, I've been working on taking all the Hardware off my MKH LP Custom, and did a chrome Hardware and pickup swap. I did this to kinda match the touring guitar that Heafy used on the In waves tour.

I found this solderless set, and threw it in. The previous pickups were 81/85, so I kept the Toggle switch, then replaced everything and followed the directions.

The bridge pickup works just fine. Normal output, volume and tone works fine. The neck pickup however, is messed up. Half output, thin sounding.
Yes, the wires are flipped the right way. I just don't see what I'm doing wrong.
