Coil Tap DiMarzio EBMM Axis

[larryandrews]

Alright I'm looking to put the coil tapping ability into my axis since the pickup selector switch broke and i figured since im in there why not do this. So here comes the real problem what parts do i need and and what diagram to use?
It is two DiMarzio pickups it has one 500K Volume Pot no tone knobs i want to replace the volume pot with a push pull pot to enable tapping on all three switch positions ie Treble Rhythm and center position.

thanks again
