Can anyone help a newbie please? This is only my second project and I'm proper stuck! While cleaning out my box of guitar stuff, I came across a partially wired up Strat scratchplate that I had stored from the early 90s. Some tasty pickups waiting to be slotted into a project. I have a donor Jap 69 reissue ready, but no idea how to fit a new switch and get rocking.
Hot Rails in bridge and neck, Alnico II in middle all wired to a Vol and 2 push-pull tone pots. As I remember it, the middle pot splits the coils on the rails and the bottom pot selects neck and bridge together. There's 3 black and 4 white wires but in what order to connect to a 5 way switch? I've been trawling t'interweb for hours and not come across a diagram that explains this wiring. Can anybody point me in the right direction please?

Did you try this page: from : localhost//support/schematics.shtml? There are a lot of schematics there, maybe you can find something that will help.

Thanks for the pointer. Tried the page already but could see no schematic for the combo of pickups and pots I have here. Think I may have to simplimify...
