Ok check this, I tried to install my radio two days ago but for some reason the radio is not getting power UNLESS the red and yellow wire is connected. I'm trying to figure out is it a wire issue or something to do with my fuses. Im using the wiring harness that came from Forztech and radio is the Pioneer AVH-x2500bt . I don't want to dish out 200 dollars to get it installed if it's just a simple wire connection.
