i would like to clarify a few connections from a cheapo xovision touch screen into a 97 maxima. i have already the metra harness and the antenna adapter. is the radio pink wire "lamp in" from the picture below suppose to connect to the illumination wire harness "Red/Blue" or the dimmer wire "Red/Orange" or none. leave the pink wire alone?
from the xovision head unit, there are 2 ground black wires on this radio. the braking brake brown wire needs a ground connection and i think reverse gear orange wire needs a ground connection as well. can i connect all 4 wires together into one large wi
