Heya im a first time poster and new to guitar wiring so i will try to explain my problem as best to my abilitys:)
Iv jst finished my first paint job on one of my guitars its a single p-90 in the bridge with one tone and volume control real fancy aye:"p In the control cavity in the back there is a black wire coming out of the wood it looks like its going towards the bridge But.... There is no wire coming out of the pickup cavity (its the only other cavity on the guitar) With some research iv concluded it could be a ground for the bridge or for the pickup? But im not sure as i havent wired a guitar before. Any help would be really appricated the guitar has been in pieces for ages:"p Thanks
With all the electronics stripped out of the guitar, it pretty much has to be a ground wire for the bridge. And, yes, you'll need that when you rewire the guitar.
It's hard to tell from the photos what type of bridge this has, but it looks like a tune-o-matic style. If so, the wire probably exits at the other end into the closest hole for the bridge. From there, it either would wrap around the post, or would exit the hole to lie under the bridge.
Sometimes, there may be a tiny hole up under where the bridge sits through which the wire contacts the back of the bridge. It is possible that you painted over this hole when refinishing the guitar.
Either way, that end needs to ground the bridge via metal to metal contact. The end in the cavity needs to be grounded to wherever the rest of the grounds are wired- usually to the back of one of the pots, which is then grounded in turn to the output jack negative.
Try fishing the wire through the hole to see where it comes out. You may need a tweezers or something similar to fish it out of the hole. Once you get both ends available to you, check the wire for continuity. You can reuse the old wire if it shows to be continuous.
It can be difficult to fish a new wire through the tiny hole, so don't pull the old wire out unless it's no good. If you have to do so, use a piece of very stiff wire to feed through the hole.
Grounding the bridge is important for noise reduction, so this is not an optional step.

Heya Thanks for your reply! Your close its just got a lespaul style tail piece:p as i said before...Real fancy;) The wire thats showing is firmly in place so i wont attempt to move it but fishing a piece of wire through is a good idea actually Ill do that in the morning:).
Thats brilliant thanks alot for that ill get back soon with the findings!!
