Hello I will help you with your question,
You will need to install a clutch switch if it does not already have one and the small blue/red stripe wire from the ignition start switch position goes i one side of the clutch switch and out the other only when the pedal is fully on the floor. The blue/red wire then connects to the small S terminal on the starter relay. Any small wires with large rings go on the battery cable side of the two large posts, The back of the relay is grounded to the fender mounting and the other large cable to the starter motor goes to empty large post on the relay.
