Ecu help!!!!! (1 Viewer)

[Belize Off Road Team]

i am in the process of a 3.4L swap...the ECU and harness i have are from a 97 2WD auto and i am dropping it in my 91 4WD 5 speed. So i figured out that i probably can't hook my 5speed into the ECU but what about 4WD?

Can i pin my 4WD wires from the 91 3.0Linto the 2WD 97 3.4L?????
