I decided to put a cig lighter in my crx cuz I wanna hook up my radar detector, and it didn't come with one. So I look at the wires in there, there's 4 of them. 2 are combined into 1 with this metal prong that looks like a Y which seems to be the one that goes to the cigarette lighter assembly. One of them goes to a light bulb, and the other was just a free wire with a plug on it. The only wire getting power according to the multimeter was the free wire. I checked the fuses and the fuse is good. How do I get power to that Y looking connector? I'm guessing one of the wires is pos and the other is neg?
