What do you mean to wire it? You would just run the same three wires to the same three contacts.
If there are dual headlamps, both hi/low, then you splice in wires for another connector so that you can power both.
If one is high only, and the other low, then you splice an extra wire into the ground wire.
Run the "high" wire to the high lamp, "low" wire to the low lamp, and one ground wire to each.
If you don't know which is high/low/ground, download the service manual from
www.sv650.org or buy a cheap CD manual off eBay.
