I see, but of course that's depicts the left side headlight socket. One wire being the ground, high beam and low beam. The other just daisy chain to the the right beam. I doubt you'll find a socket with dual wires coming out of it, just split or splice the others with the new one. Make sense?
If you're on the market for a new one that's priced right. You can't go wrong with these.
