I need help wiring the actual rings inside the halo projector. the lights are already installed I just decided to finally connect the rings. I have a 99 sentra and I more or less need to know which wires are for what.
You should have a pair of wires: red and white or red and black. That's how mine were on two separate sets. Either way, red wire goes to 12v and the black or white wire goes to ground. A number of people wire them to their parking lights. If you choose this method, there are 3 wires on your turn signal light socket. The black wire is ground. Out of the two remaining wires, one has 12v when the parking lights are on (you want this one) and the other has 12v when the turn signals/flashers are turned on. A test light will help you find out which is which.
