OBDII to OBDI conversion
OP is wanting to convert from OBDII to OBDI. All that is necessary, and that has already been posted, is the correct KS and PCM with correct trans or at least have PCM flashed for correct trans. This is what I was told to do when I did my conversion years ago (since changed back to OBDII for smog check reasons), it worked and that is all that is needed.
I know, I'm doing the same thing. But what I've read in this thread is different from what I've read elsewhere including shoebox's site. Funny thing though, I've never seen an actual write up and nothing at all about the actual wiring change itself. Just that it has to be done.
I thought that's why Ion's conversion is so expensive, guess not. Maybe I'll just find a PCM and knock sensor instead of the $250 version.

Right out of the horse's keyboard...
Like I said, its been like that since I put the 95 computer in back in 98.
You don't want the knock Module, you want the knock Sensor. It's p/n 10456126 and it goes for right around $50 from Summit.

Change the PCM: disconnect Battery, Unbolt PCM bracket from car, pull OBd2 pcm out, unplug the 4 large connectors on the OBd2 pcm, set OBd2 PCM aside.
Pick up the obd1 pcm: Plug the 4 large connectors into the obd1 pcm, shove the pcm back in the car, bolt it back in.
Change the knock sensor: On the passenger side of the engine down by the starter unplug the sinle wire from the OBD2 knock sensor, Now unscreew the OBD2 knock sensor from the engine block, coolant will leak out if the cooling system is full, screew the new ob1 knock sensor back into the engine and tighten, plug knock sensor wire back in to knock sensor. reconnect battery
Now load your tune.
Now drive and have fun.
DONE
Mine runs great and I was able to load my tune and data log with this cable http://www.moates.net/aldu1-and-cabl....html?cPath=64
I used madz28/ madtuner for the tune. He sent me tunercat link to read and write the tune to the pcm, I used tss datamaster 4.0 to do the data log and then send data logs to madtuner for him to check it. All finished, car runs great, runs better than the obd2 tune I had done originally by someone else.
Thanks, now i get it
It took 20 seconds to do that, by the way.
Lawhead, ANY pcm out of ANY 94 or 95 LT1 powered is the same, $40 at u-pull n pay. The one in my car right now came out of a 94 roadmaster, same part number as mine. If you get one out of a manual car, give me a shout and I can come change it for ya, and anything else, egr and all that other stuff.
