Hey guys

First post here... kinda. Was locked out of my other account as I forgot my password (ugh). I'm currently trying to wire in an SG400 bridge humbucker into my Squier strat (I'm aware this is for Pitbull guitars but I'm hoping you guys can help).

Currently I have somehow managed to wire it in in such a way that the ground is not working? I don't get any sound from strings and it seems as if I get a lot of hum unless I touch the pickups or hardware... which research tells me is a ground issue.

Anyway, I've attached photos... I'm hoping I've wired it in correctly (Pickup is around the wrong way in the pictures, but will be fixed). Can anyone point me in the right direction with correct wiring?
