Default Re: 4.0 6 cyl aftermarket coil pack plug lead orientation?

Note on the EDIS system each ignition fires 2 spark plugs simultaneously; one spark plug on the compression stroke which uses most of the ignition coil energy and one spark plug on the exhaust stroke that uses very little of the coil energy. The two fired plugs are connected in series with one firing negative to ground and one firing positive to ground. The four pins on the coil socket on the inline coil pack are also:

Pin 1: Cylinders 1 and 6
Pin 2: Cylinders 2 and 5
Pin 3: Cylinders 3 and 4
Pin 4: VPWR


THE ECU when receiving a signal from the camshaft position sensor also checks to see if the two related coils have fired and, to prevent two cylinder misfiring and destroying the catalytic converter when the unburnt fuel from the 2 cylinders explodes in the converter, and if not turns off the two injector associated with that coil.

I just can't see the V6 one with the different coil configuration and socket pins working on your inline 6. The ECU will shut the injectors down.... or if not you will get that explosion in the cat.
