Well it depends on the configuration / switches & pots and if anyone else was in the guitar prior to you getting it. I would suggest looking at the wiring diragram that meets your confiuragtion, they are easy to read. so just follow the wire colors and you will be fine.
You can also test this with out install it fully back, I would say, remove trem, remove pickguard, flip over install new pickup, then you can plug her in, use a screw driver to touch the poles on the pick ups, to hear if it works.. if ok put all back together , then go get a snack, because you will be playing this pup all night.
