I sorted it out.. No one could seem to give me much info but any who I have it sorted. I bought the omex rev limiter single coil with three wires. Blue,red and black. On the st205 on the coil pack you have a BLACK heavy wire and a WHITE wire with a blue tracer, basically connect the RED WIRE to the BLACK coil wire.. The BLUE wire to the WHITE wire with the BLUE tracer and the BLACK wire to a good soild ground and there ya go job done!
