Engine/Transmission (1998.5 - 2002) Help on ECM part # needed

[Gary - K7GLD]

I have located a possible ECM for my '02 HO truck, but it is from a '01, so need a lookup to see if it interchanges with mine - the numbers are:



P/N 3947912

ESN 56873429

ECM Code J91104. 02



Anyone have a clue as to usability of this on my truck?



TIA

Sorry I have no advice, only a question. What happened to your truck when the ECM went out?
