Your opinion please? VERY interesting ques. I have a 94 Z28 and just bought a 95 LT1 setup with the harness/computer. I wanted to replace my 94 engine with the 95.
I put the 95 setup on the car and hooked all the harness and everything, but there was one plug on the 95 harness that DID NOT EXIST on my 94, it's the "C105" plug, which came on 95-97 engines. Please take a look here and click at the "C105" link at the bottom of the page :
http://shbox.com/1/harness_connector_faces.htm
To make the story short, I thought the engine will start without having to plug that C105 (Which I have no where to plug it to plus I didn't know what it was), but the engine wouldn't run, it would keep trying to run but it didn't.
Now, I have a 93 Harness/computer in my garage so I thought to give it a shot. I replaced the 95 harness/computer with the 93 (Which didn't have that C105) and guess what, the engine started right up. The 93 LT1 harness came WITHOUT a MAF and I'm not sure if I want to run it that way.
What would you guys do if you were me:
1- Keep the 93 harness on that 95 LT1 that is on my 94 Z28 and SHUT UP?
2- Find a 94 Harness/computer to match my existing harness?
3- Find a 95 harness (Fuse box and all the harness that's on both sides of the engine bay) that will match the 95 LT1 and it's harness to hook that C105 into it and basically make my 94 a 95?
Is there a conversion kit to fix my problem? Any help/opinion would be greatly appreciated.

The OBDI vs. OBDII shouldn't be confusing. 93-95 were OBDI
If I were you, I would have got a 94 PCM/harness, but since seems to work with the 93 harness, then do that. You can always have the PCM tuned for speed density.
