I have read a post from 2008 about how costly this could be on a 2002 f350, but I am curious to see if any else has thought about if it is possible with only minor changes, like if the PCM is the same, it looks as if the harness can be modified to accept the gpcm. The reason I want to do this is the reliability of it, I have replaced lots of relays and getting tired of it, any help would be appreciated.
