PCM Replacement on 1994 Dodge ram 5.9l
So I have it down to the PCM which needs replacement. Question is, do I need to re-program the old OBD-1 computer? Can I use the unit straight from Autozone?
If the new one is set up for your engine size, and trans, just stuff it in, no programming involved. (mainly because, you can't....)
I wouldn't trust an autozone PCM though.... I would check junkyards before I would buy one from them.
