Working my way...one wire at a time.

I don't think I need these 2, but wanted to confirm.

I am carbureted 347.

thanks,

Coil-tach goes between your tach and your coil (obviously), so the other end of that wire is in the dash harness. Are you connecting those by some other means? Yes, the EFI wire is irrelevant to you (provides a wire to connect an EFI tach output to your tach instead). The tach just needs one signal.

Hey, Alec!

The speedhut has a wire to the tach, so yes another way.

I am using the other orange "Coil or EFI" wire to the positive terminal of my ignition coil.
