Wiring Diagram For K11 1.0

Does anybody where I can get a wiring diagram showing wiring to coil packs?
I want to wire up a tachometer and the adaptor needs to be connected across the coil packs.
You know if you get the instrument cluster with the integrated revcounter that's is just plug and play. 2 scews to remove the shroud and 3 to remove the cluster itself. Just a thought.
