To determine cable rotation, note the rotation direction of the tach drive socket on the engine while looking at the engine. If the drive socket rotates clockwise, a right lay inner cable is required. If the drive socket rotates counter-clockwise, a left lay inner cable is required. The rotation direction of the tach needle does not affect which lay should be used.
