There's information out there, it's just not going to be plug-n-play. If you have the MiniTec K20 conversion harness, the wires should be labeled. That's probably about as close as you're going to get to installation instructions. If you can't figure it out on your own, I suggest finding a custom car builder or auto electrician and getting some advice or help. 

HAHAHAHAHAHAHAHAHAHAHA!!!!!!

Maybe folks around here don't know what a "hondata ecu" is or does, or what a "super fast Mini wiring harness" is. Although you didn't actually say, it sounds like you are putting a Honda lump in a classic Mini and that your wiring harness does not mate up with the ecu unit you want to use. Most Honda conversions I've read about try to use the type ecu and harness came with the engine, and splice the harness into the original style Mini harness. Probably not much video existing on the subject.

any body out there

What about the boys in Royston Georgia they should be able to help or are they only involved in Miata's now.

anyone have any videos on wiring a honda k-20? I have a hondata ecu and the super fast mini wiring harness with no wiring instructions. body work is all done interior is done would like to drive it after working on it for last two years.
