thanks for that, but damn thats confusing for someone whos never seen the inside of a guitar before. Could i also just use that diagram when i'm acutally just putting in my pickup?
Well, the Duncan diagrams are about as clear as you'll find, at least they
look like the actual parts rather than using symbols. And to be honest guitar wiring doesn't get much simpler than that, unless it's a one-pickup guitar.
There's no reason why you shouldn't be able to use the diagram as a guide when replacing your pickup. Bear in mind on your V the physical layout of the controls will be slightly different, but the connections should be the same or very similar. Just take your time and follow all the wires to see where they connect, try to understand how it all works.
The good thing with a V, if it's a 60s/70s style wth a scratchplate, is that you can take the plate and pickups off as one piece and put the guitar itself safely away from solder splashes!
