Re: 2xEMG 89's 1xEMG SA HSH .... How??
Okay, having a bit of customizing EMG components and wiring, I can help you with how this will wind up getting wired.
First off, the EMG's need 25k ohm pots to work. If they are newer EMG's, they should have quick connect harnesses that plug into the back of the pickups. And if you get all new controls and a wiring kit, all of the components will be quick connect also - including the 5-way switch. So if you have the newer quick connect pickups, it would be more beneficial to get the new wiring kit with the solderless 5-way switch to make the install and wiring as easy as possible.
I did something similar in an ESP Stephen Carpenter 7-string, with a 707TW bridge, 707TW-R middle and SA-7 neck pickups. I had wired both humbuckers to 2x 2-way mini toggle switches for the coil splits. Everything was solderless/quick connect, except the mini toggles for the coil splits. Your going to have to do something similar to what I did to be able to get this thing back in shred mode again.
I can supply you with ALL of the diagrams you'll need to get this wired up, but you'll need a new wiring kit in order to be able to complete it. Send me a PM and we'll go from there.
