RE: Replace PCM
I have it in the garage now. It is the same year, the same motor size, and from a D that had ABS and the security system. I understand they all have to match to be "compatible". The plan is to send this one off to B&G for the flash and save the stocker for an if-needed basis or a resale of the D (gasp! never!!) later.
I could temp around on the spare and send in the stocker since it has the miles and vin on it already, but I'd rather safeguard it since I know it works.
