I have acquired a digital tac and would like to install on my 73 , there are three wires coming from tac , white , red , and just bare wire . Would anyone know where to install wires ? Thank you in advance
You can probably google the wiring diagram based on the model #. That being said, my guess would be Red is 12v+, White is Coil (terminal with wire from dist or Tach output if HEI) and the bare wire is ground.

^^^THIS. Note that the bare wire is the shield for the cable, which helps prevent radio interference.
