Radio Wiring

[Ben Swann]

I'd like to offer any info. I have as well as get some clarification, as I
have a Wiesbaden (aka AUDI and looks like a newer model of a Blaupunkt)
stereo sitting in front of me.  I will likely install it temporarily into a
'90 Coupe Q that I will be driving home in a  few weeks - need tunes for the
ride and current stereo's tape is inop.

 

SO hopefully it will be plug and play, but here is what is in back of mine:

 

Three connectors similar as described below -

 

Top Red 10 pin is obviously for power connections with pin 5 having brown
wire - ground ;  pin 8  is Red with silver stripe is most likely power;  pin
10 is Blue with green stripe and I figure to power an amplifier for the rear
connections.

 

Note:  the pin numbering on these connections is odd on one row and even on
the other.  Topmost row is even - numbers are embossed on face of the
connectors.

 

The middle connector on my radio is a brown 8 pin and 2 pair of light green
wires are obviously the typical front speaker wires.  These are pins 3&5
solid light green (+) and pins 4&6 light green with black stripe (-) as per
typical speaker wiring.

 

The bottom connector is black and has four sets of wires.  This is the
confusing part. There is a pair of red wires coming out of Pin 7  the two
wires are different size - I'll call them large and small (1 and .5 mm?).
Pin 8 has two small (.5mm?) brown wires.    Pin 5 has two small white wires.
Pin 6 has just one large gray with blue stripe wire.

 

So I gather the set of 4 wires is for the rear speakers, but wiring does not
make sense unless the different sized wires were used just to take advantage
of the particular type of wire Audi had at the time.   Perhaps someone has a
wiring diagram to make sense of this, or knows for sure.

 

I suspect the top, middle and bottom connectors could be different depending
upon stereo make.  The connectors are "idiot proof" so one can't mix up
where they are plugged in.

I have no idea what a melborne radio is but I have the schematic

sitting in front of me.  The bottom of the page says 1990 coupe quattro

and there is a vin split.  I have had my radio out in my 1991 20V and

remember the three connectors but not what color they were.  On page

91-10-2 it shows three connectors, a 10 pin one and two 8 pin ones. 

The top (10 pin) says rear speaker connection - not amplified. the

middle says front speaker and the lower one says power supply

connections.

 

It looks like all the connectors have at least 4 wires in them.
