I decided to clean up my EFI installation a bit and converted to these ignition coils from a Cadillac northstar engine. The coil pack has a built in ignition module which I bypassed, so they're controlled by the Ford EDIS system. The spark plugs are run through plastic tubes and wrapped in 'ClassicBraid' split wire looms. A nice benefit of the coils is that they use standard HEI style terminals rather than the oddball two-piece EDIS ones...
