    What tach source should I use inside the engine bay? If it is just one of the coil packs - which wire? (There are two - a red and another varied color on each pack).



    Thanks!

    You can go to any of the injectors or coil packs and use the uncommon wire which would be any of the wires that are NOT red.

    I used the rear drivers side coil pack. I believe the wire was green.

    I used the wires at the crank trigger.
