its 93 for EGR in cali actually 94 fed. 90-92 only has one o2 sensor to buy....94 and below 4.0L makes it the easiest, but watch out for the 94 with California emissions. Make sure if you end up getting a 94, that it comes from a truck with Federal emissions. They are 2 different injection programs, and 94Cali and 95+ have and EGR.
I just had a hell of a time with this when i changed my engine. It's some what explained in this thread.

The be honest, I dont really know what any of that means.the 4.0 switched to the 8-bolt "lightweight rotating assembly"
(essentially a 4.0SOHC crank and lighter OHV pistons) sometime
in the latter half of 1997.
I specifically chose a 1993 4.0 engine for my swap because 1993 while it had dual HEGO's was the first year they had an active data link, whereby a real scanning tool could distinguish more than what the PCM considered "normal" sensor values.
'93-up the raw data is output to the scan tool so the user can determin if an "almost normal" value is dead wrong for the current conditions.
1993-1994 is almost "EEC 4-1/2" by comparison to
the earlier EEC4.

Thanks. Makes alot more sense now. Esspecially that part.If you are converting a Gen1 2.9 truck to a 4.0 you really don't want to get involved with an engine (or management) newer than 1994.
