Will a 96 lt1 work in a 94 car with a 94 harness?

Will the PCM just ignore the rear o2's and crank position sensor?
Knock sensors need swapping?

That's exactly what I thought. Just needed to be absolutely sure, knock sensors the same or different?
It might only be the flexplate. I'm gonna get in there hopefully Tuesday. It is NOT a transmission problem, I brought it to a reputable transmission specialty shop today. They told me definitely motor noise NOTHING to do with trans. So it's either cracked flexplate or spun bearings/lower end damage, also I believe the oil is coming from the rear main or the rear main housing. Gonna investigate that too. Arrow

My 94 Caprice came to me with a 96 drive train and harness in it. The guy who did the swap did a bunch of wiring to add the OBD II connector under the dash. Not sure if this is because of the swap or because he was a hack (most wires were spliced with wire nuts Surprised ), but the rear O2s don't register and has to have sims run.

The only connector that will not be on the harness is the Crank position sensor. Just leave the sensor in place, and ignore it. You use the 94 cats, so no worries about rear o2s. The only thing I question is if the Knock sensors are different. But if they are, just swap them. I think you need to use the coil/ICM assembly from the 94.

I'm gonna go pick up that 94 engine I sold Dave and that he has for sale,
It might only be a flexplate issue, but I'd like to have a back up motor anyway.

Is there anything preventing you from swapping the timing cover and required components from the 96 engine to a 94?

I think the cam has a different end correct? Something about how the opti mounts and the crank sensor are the only differences. I'm sure you could swap stuff. If I was to put a 96 in I'd just leave the sensor unplugged. I think the best course if the engine is junk would be to just take your 94 engine and drop it in. It was s strong running engine when I pulled it.

'94 PCM doesn't care about rear O2's or crankshaft position sensor.

Yes, must be swapped. They are not compatible between the OBD1 & OBDII PCM's.

You can, but use the '96 coil & connector if they are available - the later piece is an upgrade from the '94-'95 coils.

No.

Opti is the same all '94-'96. Crankshaft hub was shortened by .050 in 1996 to accomodate the crank position reluctor. However you choose to mix & match parts, do not use '96 hub without the reluctor, or the '94-'95 hub with the reluctor.

Thanks for all the info!!! I have the complete 96 lt1 with harness and accessories with 53k miles out of my old dggm b4u, it has sentimental value to me and I'll probably wait and install it in my black 96 caddy when that engine goes. The dggm engine is knocking like a bastard, something definitely wrong with the bottom end or flexplate. I'm gonna pick up the spare engine just incase. But will do all possible to not have to yank this engine out.
