B) Unplug the first harness from the DME. The one with the sliding lock mechanism. That unplugs the ignition harness. No fuel and no spark. No need to unplug all the individual connectors.

Definitely don't disconnect any fuel rails.
Ok so you would do Step A prior to starting your OFHG change. This way you starved the fuel in the car system and there will be no fuel mixture to be ignited when it comes to cranking the car.

And B seems pretty damn simple.

I guess my method would of worked (and yeah without touching the fuel rails), but is just more complicated and long!

Thanks!
