Any particular reason you want the electric start to work seeing you were able to pull start it. You will probably find the alternator won't work so you will need to be able to charge the battery every once in a while, depending on how many times you start it. As for the wiring, battery positive goes to one side of the solonoid, the other side of the solonoid goes to the starter motor and the negative side of the battery goes to the chassis somewhere or directly to the side of the motor.
