I have just got a 944 S2 (1989) and the radio is wired up incorrectly. Does anyone know the colours of the wire that designate front and back, left and right speakers..? Any info much appreciated!!
Left front, white plug, white + white/brown wires. Right front, black plug, black + black/brown wires. Left rear, yellow plug, yellow + yellow/brown wires. Right rear, red plug, red + red/brown wires.
