I just got an OEM fog light switch to hook up to my fog lights (duh). My question is what prong on the back does what? There are five, I am assuming one is ground, one is for the indicator light, one for the interior light, and two for the actual switch. Or is there any where I can just get the plug? I found the entire harness online, but I would just need the female connector in the back of the switch. thanks
