I've got a few emg wiring questions. I'm looking to put a emg 81 and 85 in my 10 year old Ibanez RG470 that has passive pickups now. The guitar has neck and bridge humbuckers and a single coil in the middle. I'm planning to disconnect the the single coil but leave it in so there isn't a gaping hole, but would I need a different switch than the 5 way one on there if I had just the 2 pickups?

The guitar also has 1 volume and 2 tone controls, but I haven't been able to find a emg wiring diagram for that for an 81 and 85 setup. I checked guitarelectronics.com like BLS recommended in this thread but no luck. Every diagram I found was either for 1 vol and 1 tone, 2 vols and 2 tones, or 2 vols and 1 tone.

Lastly, did all you guys just cram the battery in wherever you could fit it or did you make a special spot for it?

I'd really like to do this installation myself to learn how rather than take it somewhere so any help would be greatly appreciated.
