With the ASI, only the speaker wires go through the 9pin plug. Starting in the top row of the 9pin plug from the left: red: front right, green: rear left, white/brown: common right going to the rear, middle row: white/red: common right going to the front, white/green: common left going to the rear, brown: rear right, bottom row: white/orange: common left going to front, orange: front left. All of this information is on a label on top of the ASI Radio. The white/red wire coming out of the back of the radio splits into the white/red and white/brown wires before going into the connector, likewise, the white/orange wire splits into white/orange and white/green. The white wires are negative and the solid color wires are positive. Also coming out of the back of the radio are the black antenna coaxial cable, the black ground wire, the blue dimmer wire, the white power antenna wire, the yellow 12 volt switched wire and red 12 volt constant wire, both of which go through inline fuse holders.
