What kind of "school research" demands that you use the wrong part for the job? If you already have the pickups and don't have the coin to replace them with more suitable pickups, that's cool, but if you're just throwing the pickups at the guitar just because you think it's cool to be different, I think you're throwing your money away.
Anyway, regardless of what you pick, you'll need two 500k ohm pots, a five-way Strat switch, a mono jack, and a .047uf cap. You can use this diagram to help you wire up the pickups. However, on the EMG, the red wire is the hot wire and the black wire is soldered to the white wire and taped off. On the 498T, this pickup uses a braided shield cable as the ground and the center conductor is the hot wire.
If the in-between sounds on positions 2 and 4 sound very thin, reverse the wires on the EMG and the JB. Ground the red wire on the EMG and the black wire on the JB and the green wires on both will be the hot wires. This is much easier than trying to swap the phase on the 498T with its braided cable setup.
Good luck, and I'd really recommend re-thinking those pickup choices. JB's turn to mud in the neck and 490's/496's sound better in the mid.
