74 grand cherokee firing order

I need to know the firing order and a diagram for wire placement

Engine size would be helpful.

Its an inline 6 cylinder we've shortened, removed the body built a complete roll cage from front to back, fuel cell,rad in the rear, 35" super swampers but we just can't get the firing order right. PLEASE HELP!!

I'm thinking it's the 4.2?
