supposedly, this engine is a 95 but on the harness and on the oilpan, i see what appears to be that oil change sensor in the side of the pan.

was't that a 96+ thing? any tips or tricks for me to differentiate what year this setup is? engine and/or harness????

also i have a 95 computer, if the harness is a 96 will it work on a 95 ecm?

 

the sesor on the side of the oil pan is the leval sensor. and my 95 has it so its not a 96 thing, i dont think a 95 harness will work with a 96, one is obd1 and the othere is obdII

 

sweet, that makes me feel a little better then. any way to tell the year of the engine?

where do lt-1s have the block casting numbers? can you find out what year it is like that?

 

My 94 also has that sensor. The engines and harnesses can be mixed and matched. The 96 will have a crank sensor that obd1 cars didn't have. I think the 96 also has 2 knock sensors. 96 will also have 2 extra O2 sensors. My casting numbers are behind the drivers side head before the transmission.

 

dooh. i forgot all about the post cat o2 sensors on obd2.

it is obd1 then. but strangely it does have 2 knock sensors. and 2 o2 sensors but no post cat o2 sensors.

thanx a bunch. i appreciate it.
