Does anybody know where there could possibly be a list/info on what PCM service #'s and/or hardware numbers and what they contain? (ie efan control, DBW/DBC drivers, ect...) I am trying to figure out what PCM I could incorporate to run electric fans on 2001 year 5.3L setup. Im not sure if you can change a PCM that wasn't originally setup for e-fan (early pickups) to operate one. I have changed settings in my PCM fan on/off temps but am not getting any relay control from the PCM.
Thanks in advance!
