Thanks for the emails.
The part that is tripping me up is the 97 NAS sub wiring harness. That is the part I am after now.
In case anyone is interested I have a 1997 300 Tdi AC harness that we made that allows the 97 NAS AC system to be used with the Tdi, no wiring mods. Will trade that for the EFI version, or will buy the EFI version.
I do not check PMs. Call or email if you need something.
