FYI - There is a library in New Mexico that allows public access to chiltons:

iam having the same issue. 2005 300c ecm won't detect the key cycle for some reason. harness works for flash other years and models but won't detect key cycle on this one. I know on the ford stuff when you cycle the key it sends 18v to some wire supposedly but when I bench flash most my ford stuff I just unplug the ecm plug and plug it back in quick and it works every time as a key cycle. however on this one it won't trick it into working. Does anyone know what wire the hp tuner sends 18volts down turning the key off? that way I can just simulate it with a 18v power supply.
