Engine/Transmission (1998.5 - 2002) Nice or not conversion

[Shun70]

Ole man killed my 99 cummins with gas. So now 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

I know the 98.5 and 99 are a strange animal, Some of the wiring is different soo i would use the pcm ecm and wire harness from the 2001. Some of the wires to the transmission use different colors on the 98-99 but they all have 8 wires. Good luck and welcome to the forums, I am sure some of the guys who have done this switch will chime in, if they see it seems most have bought newer trucks and the second gen's get forgot.
