RIPP replied to a customer review having the same confusion with this:
"Hi Christian, your right, the coil comes from our 3.8 V6 kit and therefore the firing order is for that engine. We are retrofitting that to the 4.0 and that's where the confusion lies. There should have been an instruction pack showing the correct firing order and it sounds like you may have missed it or it was missing, that would have made this clear. Sorry about the confusion and thanks for sharing"
@tx-skydiver , I think your firing order may be fucked up. If you're going to stick with this system, double check. Personally, I recommend you ditch that junk and find an OEM rail.
