Finally got to get to an engine swap on my 92 w900l. Its a series 60 12.7 liter. I think I may have a ddec 3 or 4 ecm. Its completly different than my ddec2 ecm on my donor engine. Both ar 92 year so should be ddec 2 right? Below is the pictures of the ecm which came off my engine im replacing and i suspect to be a 3 or 4 ecm. I guess the up side is my cab has already been rewired so the jakes and cruise will work which they both did! The down side is im gona have to change engine wiring harness from my 92 kw engine to my donor engine. The donor engine is from a 92 pete.
