There's a blue wire going to the back of the cluster that you supposedly can tap into. I couldn't find it so I spliced into the dizzy plug.

There are two plugs at the dizzy. One plug is smaller and only has two wires in it. The blue wire on this plug is the tach wire. Just splice into it and ur golden.
