Re: Pickup wiring... help? =)
It will take a while, but look inside and draw a diagram of the wiring schematics. Double check, and triple check that you have everything correct. Then when you install the new pickup just duplicate the connections. Since they're both 4 conductor pickups it should be a snap.
I've changed pickups in previous Ibanez guitars many times. I could never remember, so I had to draw it out every time.
My soldering skills have always sucked, and it looked terrible, but it worked. Now I just have them done professionally.
