I'm going to be performing a M6 to A4 swap in my '96 Z28. Right now I'm researching the wiring issues before I begin to purchase all the necessary parts.

I've already talked with someone that has done this swap and the easiest way to get around the wiring issues would be for me to just swap in a complete LT1/4l60e harness and PCM.

I already know that a '94 harness differs from a '95. My question is will a '95 or '97 harness work on my '96???

Anyone know???

You want a 96 or 97 harness for full functionality.

A 97 harness has a different coil connector. 96 would be ideal, but 97 will work with some minor modifications.

I was about to post this exact question:

I am going to be doing an M6 to A4 conversion and I would like to know if there is any difference between the 95 TA harness and the 96 Z28 harness? Thanks Guys! sorry to hijack..

96 and 97 coils are the same, so the connector should also be.

I am going to be doing an M6 to A4 conversion and I would like to know if there is any difference between the 95 TA harness and the 96 Z28 harness?

Is the harness just a transmission harness, and does it go to the back of the PCM? Or do you mean replacing the entire harness?

Yes, there are differences between 95 and 96.
-coil plug is different
-96 has an EVAP vacuum switch, crank sensor, rear O2s -95 does not.

It is an engine/transmission harness.

Rob, the gentleman that Im going to do the swap with is willing to purchase a 95 A4 harness, just my luck! Thanks
