I've been planning on doing a little accent lighting in my car. So my switches came in weeks ago and my lights (LED strips) just finally got here. The switches have 3 connectors (power, ground, lamp) and the lights have to wires (power, ground). I'm going to remove the cigarette lighter on the shifter bezel to put the switch in and take the power from there. But can I attach the ground wires from the lights to the switch on the same connector as the ground from the main power?
