Do you have the starter switch on the steering box? Run large thick cable fom the neg side of the batteryto one terminal on the switch and the same type camle from the switchto the starter. Run wire from the neg side of the bat to a coil resister and then to the coil. You need to make a loose connectoin in the coil wire system so you can shut it off. You also need a big ground wire from the pos side of the batery to ground. If you don'thave the starter switch,get one or a solinoid.
