2nd Gen Non-Engine/Transmission 99 cummins replacement to 2001 cummins install problems

[Shun70]

I am trying to change my motor from the 99. Cummins to the 2001 cummins. I noticed that there is no crankshaft position sensor and it is blocked off where the 99 has it. How can I get the 2001 cummins to run. Do I need to use the engine computer from the 2001 with the harness where there is no connection. Do I need to use the anything else from the 2001 to make the engine run in my 99

you need to change the software in the ecm to 2001.

Software question 99 to 2001

you need to change the software in the ecm to 2001.

Can I use the exam from a 2001 motor? I also had to use the 99 engine bay harness because of a few sensor connection differences but they were the same sensors:-laf
