What do you have for ANY wiring, that is you have it rigged with a toggle panel, etc, so you can run it?
As shown in the diagram, the one terminal on the VR goes to switched 12V "ignition run". It branches off to EITHER field terminal. The second field terminal hooks to the remaining terminal of the VR. VR MUST be grounded to battery neg. MUST. A good way is to install a ground cable IE "Ford style" starter/ eyelet to eyelet cable from rear bolt hole on driver side head to firewall, sometimes master cylinder studs work good for that. Remaining wire is output, at big stud on alternator, goes to battery. I'd run at least no 10 for stock alternator, either a pair or 3x not 10's in parallel or no8 or larger
