AZ Desert,
Welcome. I believe all you need is tach wire under the hood, it has its own hole that would need to be drilled in the firewall. Dash wiring of coarse.

69hemibeep, thanks for your help, the dash has a complete wiring harness with it. Will I need a special harness for the coil to the tach lead?
