I emailed the guy on EBAY and he said he simply reverse engineered GM's harness to work as a stand alone. This is the same thing PPE does from what they told me. I've looked at the factory manuals for an 02 and it looks pretty straight forward to do the re-wire. The good part is that most of the DMAX harness is already stand-alone with just a few connections to the truck. The BIG hurdle is the PASSLOCK and BCM. The PPE XCELLERATOR and EFILIVE both can program this out, but you MUST hook in an OBDII port to do so. Or you could send your ECM to an EFILIVE programmer to have the BCM and PASSLOCK overridden. This will allow the ECM and TCM work together, but won't allow the transfer case module to work as it hooks into the BCM.
I've been doing ALOT of homework on this subject as I have decided to deep six my 6.5 and go with a DMAX in my SUB. Just looking for a good donor at the moment as I want to go with a LB7, prefferably an 01-02 as they are MUCH simpler to wire in and don't have any of the DIC to worry about.
