Hey mate we might need to see a picture. Even if those wires are around the wrong way on the jack it will still make noise, so I'm not sure you have that correct. The inside 'tang' on the jack needs to go to earth. The outside one goes to the middle tang on the first volume pot (in standard wiring).

Anyway, if you can show use what you have it'll be a lot easier to work out what's going on that trying to describe it.
