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?
