    Default tach wiring routing

    Hey guys,
    The PO(s) cut a lot of the factory wiring in the V8 conversion of my 73 . I'm trying to locate where the tach wiring might have exited the firewall to the engine bay. I'm looking for a BLK/WHT". I think this one would have gone to the positive side of the coil.
    Thanks for any thoughts.
    Happy Motoring today!

    If it's like my '78, the wire comes through the firewall on the driver's side near the brake booster. The tach wire goes to the NEG side of the coil.

    Good luck, neighbor.
