Subject: E36 stereo radio connector

Here's the Pin Assignments for the E36 radio. This is from the factory Electrical Manual and is valid for E36 cars from '95 to the present. It also MUST be noted, for all the people who want to upgrade their radios, the factory radio is only a tuner, (ie. it has no power to operate speakers.) You must pick up the individual speaker wires from the amp which is located in the sidewall panel on the left side of the trunk. The radio connector only has the left and right, front and rear speaker power supply wires to the amp.

Pin #1- Left front speaker output (+)---- color: yellow/red Pin#2- Right front speaker output (+)----color: blue/red Pin#3- Left rear speaker output (+)----color: yellow/black Pin#4- "Mute" for the telephone color: white/brown Pin#5- Power (Hot in ACC and RUN) from fuse # 44----color: violet/white Pin#6- Right rear speaker output (+)----color: blue/black Pin#7- CD Changer (I-Bus)----color: yellow Pin#8- Left front speaker output (-)----color: brown/orange Pin#9- Radio Memory Power (stations etc.) (HOT at all times)(from fuse #9)----color: red/white
Pin#10- Variable road noise volume adjustment input (from the tach)----color: black/white (with HK system, this is only on with Hi-Fi switch on) Pin#11- Right front speaker output (-)----color: brown/orange Pin#12- Left rear speaker output (-)----color: brown/orange Pin#13- Radio lights (from dimmer and headlight switch)----color: gray/red Pin#14- Right rear speaker output (-)----color: brown/orange Pin#15- Ground
Pin#16- Antenna amplifier output----color: white

Hope this helps,
