besides i can't seem to get the screen to turn on. there is also another problem. i have no blue wire for accessory, i have a green, red, purple, ground, and then a white, i have no idea what the white one needs to go to? i tried giving it power and it started to turn on the starter if that helps. i really have no clue. i also have the harness.

thanks for any help

i have an avenger, needs a turbo though.
