Almost positive you can use the SteveKen adapter kit for the trans. The wiring shouldn't be tough, the technology isn't that advanced for an 04ish car. Just use the W12 cluster and wire it up correctly.

The technology IS very advanced, even on a 2001 D2 6,0 A8L. The cluster's just a minute part of the jigsaw. To run the W12 cluster, you'll need to have pretty much the whole wiring, or at least the main (central) one, which is the dash harness.

I've rewired a D2 6,0 W12 that had suffered a minor dash fire. It took close to 4 weeks to get it up and running, making a new harness. Bear in mind, this car actually came with a 6,0 W12, yet it was a pig to rewire, and fought back every step of the way. After she ran, it took me a further week to eliminate bugs that had the cluster glowing like a Christmas tree.

It's not an easy job.

So how many wires go to the motor? Can't be more than like 50. Most of them are like "oil low light" or coolant temp. The only real input that the motor sees is the throttle and power

If only it was that straight forward, but it's not.

So what other inputs does the motor see? How many wires go through the harness plugs?

I can't imagine the ECU needs much to run outside of the car. What are you putting it in? The only input is the throttle really
