You will need to verify by testing lamp. I beleive the single top pin is ground. The two pins are the power. Drawing is on some of the socket packages.
I would still get one like you showed from Summit. That way you only need to do testing once.

Its a four headlight system so each bulb only has two prongs.In other words low and high beam has there own individual bulbs.
