Radio Connector

From Bay 13


--------------------------------------------------------------------------------





My lack of knowledge concerning after market CD changers has prompted me to develop this hopefully helpful guide for Volvo owners that are trying to find various signals on the connectors on the back of the radio. This layout is taken from a 1995 schematic, I will check newer schematics to see if the lay out and wire colors have changed. 16/1 is the circuit designation for the two connectors. The two connectors are further broken down to "A" for the 14 pin (larger) connector and "B" for the 10 pin (smaller) connector. Lead colors are shown by letters: SB = Black, GR = Gray, W = White, R = Red, BN = Brown, Y = Yellow, P = Pink, BL = Blue, GN = Green, OR = Orange, VO = Violet. To further break down the 14 pin "A" connector: 1A = Dash Left Speaker +, 2A = Dash Left Speaker -, 3A = Antenna +, 4A = Battery + 12V, 5A = Not used, 6A = Ground, 7A = Dash Right Speaker +, 8A = Dash Right Speaker -, 9A = Not used, 10A = Rheostat +, 11A = Rheostat Ground, 12A Battery + 12V , 13A = ACC +, 14A = Ground. Breaking down the 10 pin "B" connector: 1B = Left Rear Speaker -, 2B = Left Rear Speaker +, 3B = Left Front Door Speaker -, 4B = Left Front Door Speaker +, 5B = Right Rear Speaker -, 6B = Right Rear Speaker +, 7B & 8B = Not used, 9B = Right Front Door Speaker -, 10B = Right Front Door Speaker + . The rear speaker wires supply the rear hat shelf and door speakers if installed, wire coloring is the same for the hat shelf and the rear door speakers
