Re: tac wiring ?
I don't have a diagram, but can try to explain it. If it's a factory style tach, then it should be marked on the back. One is marked 12v, which goes to the fuse box, and should have power only when the key is on. The other is marked "coil", and goes to the "-" side of the coil for points, or "tach" side of an HEI distributor. Hope this helps.
