    I have a 2011 toyota tacoma. I have a new 4003 H4 headlight plug with three wires, 1 red 1 green 1 black. My harness has the following wire colors. 1 white with black stripe, 1green, 1 red with black stripe, 1black, 1 red with white stripe. I also have 1 black unattached wire from the DLR. All of this is on the passenger side. Now, the high beam works and the low beam works and my DLR works. Problem: Low beam comes on when parking light is turned on.

    I'm a bit confused?
    How do you have 5 wires from an H4 plug harness?

    I can't figure out what the Black wire would be, But I got the others.
