QUESTION: sorry   yes it is single fire

Answer
The yellow wire from the adapter goes to the negitive side of the front coil. The blue wire from the adapter goes to the negitive side of the rear coil. the green wire goes to the pink wire under the gages. It should have a butt connector or a clear connector on it. the red and blue wire from the tach goes to a power sourse which is shut off when you turn the key off. the black wire goes to ground.
good luck and happy riding
