Wiring an RG7420 ?

Hey everyone!!!
How y'all been. I've been busy in the studio, so I havent been online much.
Anyway............
I've never claimed to be an electronic wiz, or even a decent luthier. Im working on an RG7420 project......adding new p/u's, pickguard, etc.........

As I'm sure most of you know.........the neck p/u has 4 leads and a grnd. The bridge p/u has 2 leads and a grnd. Somewhere I am missing something or have a wire where it shouldnt be!
I wired in the neck Evo exactly like the stock p/u that came out. The bridge one, well, I have 2 extra wires now...........

The rear coil of the Evo in the bridge has very little volume, but the front coil is just off the hook insane loud!!! I attached the red and the white wires to the switch exactly like the stock p/u that was in it. The left over......the green, black, and bare......I grounded to the pot. Obviously this is incorrect!

I looked here on Jemsite for some RG7420 schematics to no avail...........and I have just about all the Dimarzio schematics printed out already, but they differ from what I'm looking at for some reason.

I guess Im counting on y'alls combined infinate knowledge to help me out here!!!!!
Any & all suggestions are as always..........greatly appreciated!

Well, first thing's first. If you're changing pickups, then the guitar's original wiring schematic isn't going to do you a ton of good.

The guitar's original bridge pickup is the typical Ibanez stock 2-wire design, or most likely, 2 wires and a separate bare ground. It should have been a red wire which is the hot connection and a white one which is the coil-tap. On your new Dimarzio, black is the hot wire, green is ground and gets connected to common ground along with the bare wire, and the red and white ones get soldered together and act in place of the original coil tap wire. That will give you your stock switching options and sounds back.
