    Power wires for Head Unit?

    I am having trouble getting the power wires right for my deck. The deck has the basic ground, ignition and battery. My question is what is the ignition and battery coming from the BMW. I wired it up so that It finally works, but it only works when the car isn't on, just lights and everything on. So can someone help me wire this up right. Please, I am starting to get mad, I need music when I drive.

      ....

      Ya, I got ground, that isn't messing things up. There are like 4 power wires coming from the bmw. I guess I have to buy a powerlight thing. Will that tell me the two others that I am looking for though?

      Thanx

        You want a test light. Esentially it's just a light bulb with an aligator clip on one end and a pointed probe on the other. Clip the aligator clip to a ground. Then, touch the probe to the wires under the dash. When the light lights up, you found your constant power. Then turn on the ignition and find the wire that lights the light up this way. That is your ignition on power.

          Alright

          KK, that makes sense, I can do that, I might even have one of those test lights somewhere. But the other wires do nothing? Should I just tape them off?

          Thanx

            If they aren't anything you need, tape them off and call it good. You might consider capping them off with a crimp connector just so there is no way they can short on anything.

                ya, I got that one too, I just gotta figure out those other two powers. There are three options, there is a purple and there are 2 more another white and yellow, that come out of a little box. So I gotta figure out which is which.

                Thanx for help, I will work on it later today or tommorow

                  Update

                  So I was working on my deck over the weekend and I didn't get anywhere. And I am not sure at all what to do now. I tested the wires and I couldn't find the ignition wire anywhere. One of the wires that I found is a wire for the internal lights of the car. So how could I wire up an ignition wire, because that is the only one that I need.

                  Please Help, I have no clue what is going on.
