At the prodding of the forum I decided that installing a relay system to my headlights made sense. As much as I like the "plug-n-play" feature of the EasternBeaver system I also like to do things myself. I acquired 2 nice relays and a couple of sockets and away I went. Electricals befuddle me somewhat so I have to ask simple questions. Here's the question; 3 wires on the light socket; high, low and common (ground). Low wire to one relay, high beam to the other, the new socket is grounded to a heavy wire. Do I need to connect the common wire from the original bike socket?

couldn't help you there, it's all a bit of a mystery to me.....I bought the Eastern Beaver kit instead. It's very well sorted out - all the wires cut to exact lengths, the fasterners are top quality, and the instructions are dummy-proof.
You need to have a ground connection to each relay to make it throw, but it can come from any good black/white wire ground connection or the battery ground. Here's a typical diagram. The grounds on the two lower left connectors need to go to the battery negative. The one on the upper right is already in the stock harness and is usually used for the two relay grounds but doesn't need to be. You could use the battery negative. Having the two 15A fuses is nice as it allows either the high or low beam to blow a fuse and still have the other one working. The Eastern Beaver kit uses a single 20A fuse to supply both relays.
