OBD2 to PCM
Hello everyone,
Trying to get a 6.4 into a 68 Newport. Working through all the electrical harness. I have the stock PCM and will be using HP Tuners going forward. Right now I have to get the OBD2 port on one harness onto one of the two harnesses which attach to the PCM. Any ideas?
Thanks

Didnt the OBD Connector come with the Harness you got to install all the electrical for the engine kit your installing? That would be odd if it didnt come with the harness !!!!

I have all the harnesses and that is one of the problems. I have everything from the donor car, even stuff I don't need. What I am trying to figure out is the OBD2 is on one harness. That harness with the OBD2 is not one of the ones which attach directly to the PCM. The OBD2 harness does attach to one of those but all of those harnesses also attach to the BCM. I wanted to see if anyone knew where the OBD2 harness fed into. I might just have to go to town with an ohm meter to see where the OBD2 port is feeding to. I'll try to attach pictures later of what I'm talking about. This is confusing enough with out me trying to describe my wire mess! But this is the fun part, right?

You know what, that whole book will help. I remember looking at that a few months ago. The problem I have is I am always looking up so much stuff, I forget what I looked up!
Appreciate the help, thank you

Do a web search for Hemi swaps and you should find the place.
