Rob, this looks excellent, but in it's current form wouldn't sell me. (I don't need any extras at this time).

What might encourage me, would be if the rear of the sled could be worked to include mountings for ethernet and/or USB. Whilst neither are self-aligning like the main harness, some people here have managed to do ethernet mountings...

I know this might be a little late, since you're looking at production soon, but it's just a thought.
