ECM reset

What year and model? If it's throwing codes for TPS then it may need the ignition cycled a few times to reset all the zero's on the throttle. Literally turn everything on but don't try to start it, count to three, then turn it off at the key switch. Count to three and do it again. Cycle three or four times then try it.
You installed a new wiring harness? I doubt the ecm is your problem. I'd double and triple check you have your end connections are right. Might find one or two hooked backwards..
