From the the factory you would have wires on both sides of the voltage reg,just bring them to one side and match them up on the same spade on one side.Then everything that should be powered,and then just run a heavier gauge maybe a 10 ga from the alt to the battery.I'm not sure if thats the proper way to do it but thats how I ran my 57 wagon for years with no trouble when I had a one wire on my y bock.If you don't want the reg under the hood just match up the wires and connect them together and remove the reg completly.
