I have a 2002 dodge van 3500 5.9 with a bad computer and I happen to have a used one from a 2000 dodge p-u 5.9 that when installed seems to work fine except for the oil pressure gauge --pretty sure the truck had a light and the van has a gauge anyway I need to know if I can program this computer to match the van with my 908-p any advise on how to do it would be appreciated thanks
