I got an upgraded wiring harness for my headlights from suvlights. Now I want to use the empty passenger side headlight socket to power up the relay for my auxilary lights, so that they run on high beams only. So I'm guessing that the three contacts on the socket are high beam power, low beam power, and ground. My question is, do I need to make sure that the ground is connected to a ground if I am going to use the high beam power source as a supply for my relay switched auxilary lamps? Am I right about the headlight contacts? High/Low/Ground?
