Prior owner did not supply battery cables. Where do I hookup the plus and minus? Directly to the starter.? Does the starter have a built in relay? Thanks

On mine the negative - is attached to the side of the starter. Positive + is connected to the solenoid. I'm pretty sure yours will be the same. If you post your serial number, we could probably find a wiring diagram.
