ECM non bird or cat info.
Trying to make a 90 F150 with a modified 5.0 and a standard trans mass air. Using a newer truck auto ecm with a auto trans. I pretty much got the harness part figured out, I keep reading about putting resistors inputs to the ecm to trick the computer to think it has an auto trans. I can't seem to find more info on it. So if anybody has info or where to look can you let me know. The ecm is a "HUG2" 5.0, 4R70W trans.
