You should hold the SIR coil, rotate the coil hub clockwise until the coil ribbon stops while depressing the spring service lock, rotate the coil hub slowly, counterclockwise, until the centering window appears yellow and both arrows line up, release the spring service lock between the locking tab. The SIR coil is now centered, align the centered SIR coil with the horn tower and slide it onto the steering shaft assembly.
