Halo projector installation help

I just got some halo projectors for my 96 civic but I need some help installing them. Its easy to get them in but it has two red wires and two white wires. It says to connect these to the positive and negative terminals of the parking lights. I just dont know what the negative and positive terminals are? Does it mean just splice it into the red and black wires on the parking lights?

you could splice them into the parking lights or to a toggle to come on when you want them to. Good luck

you could put those wires into the running light harness but that means when you turn your lights on your halos run all the time. however for a more better effect you could run those wires to your accessory power and then to a toggle switch to turn them on and off whenever i.e. leave them off when you pull up turn them on as you get out.
