Hi all.


I still have my '98 Ram 2500 12v Cummins that I bought brand new in late '98.
It still amazes me that it has been so trouble free after all these years and coming up on 250k miles.
That's the simple backstory.


All I'm trying to figure out is that I want to order some throttle cables and other maintenance parts, but I keep seeing letter designations of "ECT, ETB and ETO" that reference something and I can't figure out what they mean.


I don't know what my particular engine is.
Can someone give me the quick explanation of those terms?


TIA
