when you go to the 87 ecm the firing order is the same just wire it up like normal.

figured it out

well i figured out the difference; wires go on the opposite side. You switch all wires from one side to the other. Next upgrade will be my ecm. Hope everything is straight forward, I hate when I find out I have to buy a few more things for the upgrade!

ecm is straight forward. just get a IAT sensor put it by the air filter get a chip and i changed out the MAF to a 87 and your good to go.
