hi. i have a 97 3.9 dakota 4x4 AT and i put in a 5.2 from a 99 durango 4x2 AT, and the engine harness where different so i had to combine the the 3.9 with the 5.2 for the transmission and transfercase also couple of other plugs and deleted the ac plugs and few others..

so my question is, what ecm can i use?
can i use a ecm from a 97 5.2 dakota 4x4 ?

thanks
