I am in the middle of swapping out my OEM radio for bluetooth capable one, new hands free law in San Antonio. I am not using a new harness so I clipped plug off. Question is I can wire it up but now dome light does not come on when opening door or stay on after shut, and headlights dont stay on after turning ignition off. I know these are usually annoyances but I would rather have them but not. Trying to find a correct wire code that tells me what the whites and reds are for in radio cluster?
