I'm also planning this for the winter. You can re-flash your current pcm to M6 using HPT or possibly, I'm not sure, Flashcan. Wiring harness can be modified for M6 with little tricks There's a a4 to m6 thread in manual transmission section, check it out.

I might try just using A4 program with M6 by disabling codes and making pcm think the a4 tranny is on 3rd when P/N switch is not activated.

I think the following is about enough. Helm's manual will help if you want to do some other wiring tricks.

i bought an engine bay wiring harness for a 98 z28 6 speed, like i said before im planning on converting my 98 z28 4l60e to a t56, is this what i need to get the right connectios for the tranny like the reverse lights? and pcm connection, cause im not comfortable splicing my stock harness, this harness is stock but from another z28 98, im sure it will work if the pcm is reflashed to m6 usage?
