A 12v cummins is pretty much completely mechanical. Few odds and ends are electric, but they dont require a computer to run. Thats one of the reason people want to swap in 12v vs the 24v cummins.
yes I know. I was replying to his comment about using the V170. I worked for Cummins and an aftermarket diesel company for 10+ years. We did tons of swaps in various things. We even 4Bt swapped a Jeep Liberty back in 05.
