I know it is easy enough to change the harness around to correct the firing order difference. But, I did see the firing order set up menu in the 12200411 ecm. Can I just change the firing order there? Would be nice! Thanks.

it is my understanding that this table is for misfire recognition only, it will not physically change the firing order. However you will still want to change this to get misfire recognition to work correctly, when needed of course
