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 :

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.

Do you still have the 94 computer and harness? If so, I think you would be able to use the 94 computer and harness with the 95 motor. I think that c105 connector is just there to integrate traction control wiring that your 94 didn't have to begin with. Might be an issue with going from a non vented opti to vented but I think the opti harness is the same so I'm not sure about that.

yeah, i just checked the opti harness, it's the same so I can run the 95 vented one with a 93-94 harness. I do not have the the 94 setup or harness anymore, if I knew I wouldn't sell it . The main question is if going back with a 94 harness is the best shot here. Also, will a 95 computer work with a 94 harness? that's in case I can find a 94 harness without a computer yet?

Also, the pink wire is : "Power feed from injector Fuse #10" , I think that's why it didn't start, not sure if the traction control thing has anything to do with starting it, but I might be wrong.

custom95

I beleive 94-95 computer is same part number but the programming may vary a little. I think if you used the 94 harness you would be fine. You could probably modify the 95 harness to work and I would advise against using the 93 harness and computer because of the speed density vs. maf thing (93=sd- 94-95=maf).

custom95

That probably has something to do with it and I know that the traction control system is designed to cut fuel to the engine when engaged and wheels start to spin. I'm guessing that since the tc system isn't hooked up the 95 computer is "trippin" and cutting off the fuel.

mybluez28echoes

that makes sense, i think i'll go with a 94 harness and keep the 95 computer and see what happens

I think all you need to do is supply power to the pink wire in cavity B of C105 and your engine should run. Jumper the pink wire from the car harness of C100, cavity K to your 1995 engine harness C105 cavity B.
