the reverse lights work off wires on the a4 shifter harness, u have to cut that and use wires for the park/nuetral safety switch. you need to wire up the clutch pedal to that. the a4 harness can be used with the t56, you do have to wire up the VSS and if you wanted to keep the cags, that too. PCM can be flashed to m6 also, just make sure you put that A4 connected up and out of the way.
