Yup like I said in post #4 Bread trucks or step vans / concession trucks (And the links I sent you) I would search "4BT Cummins" on Ebay and truck trader. You will see tons for sale with decent mileage too. Reason I would buy the whole truck is you will get engine and trans ... and truck LOL for the price of some engines ONLY that are for sale. The common rail / allison trucks will require all their respective ECU/PCM units and harnesses but mostly all trucks are for sale complete and running. If it were me I would go after what is commonly called "P-Pump" trucks.

I was wanting to do the same thing, and wondering the same thing "electronics are just unneccesary. could I rip it all out and run a basic lights, horn, crank setup or is EVERYTHING tied into the computer? is there a way to delete the engine/trans out of the equation?"
