You could always talk to Volker, he makes stand alone ECM's for Dmax's. He made this run and tuned it as well.
Mcschwarz diesel engineering 262-725-3581. I believe he might be out of the country on business for a couple weeks.
Or you could call PPE, they can make the dmax run in anything. They can make a harness that takes a factory ECM, TCM and Trans work with 6 connections/
I have a customer doing this over the next year for his 75 C-20 pulling truck.
