HP EFI Tach Wiring I have the Holley LS1 HP EFI kit.
Instructions say use pin A28 (as did the Holley tech line) for the tach. I am running an Autometer Sport Comp tach.
Problem is, there is no wire in pin A28.
Do you need to add a wire/ pin here or can you tap off of somewhere else?
Thanks

The wire is missing on the harness, you have to move a unused wire to the tach location to get it to work.
