the trouble is all the diagrams on the net talk about which pin the wire is attached to, they don't talk about wire colours. I think your best bet would be to get out a multimeter and do some checking ...

completely offtopic and useless but when you have 5mins of spare time please ring the previous owner in my name and tell him that hes an idiot.

put it on the "voltage" setting to check for power (there should be 2 power wires, 1 is on all the time the other is on with the ignition) ... the rest you'll need to do with the "resistance" setting you'll need to find the earth (by checking each wire against ground), then you'll need to check which wires are connected to which speakers ...


... next time I take my display off (soon as I want to adjust some of the 'tronics behind) I'll take a couple of pictures of the wires, trouble is my system used to be the BOSE version so might be a bit different ...

I had this problem on my porsche when i got it some one had cut all the wires!!!!!

i called and mobile audio specialist, he put ISO connectors in and wired it up for £15

this would be the easiest option for you!

My last car had a similar thing done to it. Went to a scrappy and cut the loom and plug of the bit i needed, soldered colour to colour just so it was back to standard.

Nice plug on the end since pretty much everything has the ISO industry standard now its probably worth while

true, but the trouble is they don't have wire colours, only the pins that the wires go to so not much help in this situation ... but well worth having anyway :thumbs:
if you look at the wiring diagram all the colours are there but in italian. easy to translate using the net. :thumbs:

just click on the 156 elearn link to download it as a rar file,unpack it then use something like nero or alcohol120% to burn to disk. personally i just use winiso to mount the cue file on a virtual disk on the laptop.

is there 'any' plug remaining, or just bare wires?! you need to hope whoever cut the wires did it properly, which means cutting them one by one. it is common for 'idiots' to just use a side cutter and cut them all at once. sounds ok, except live wires short out with other wires through the metal side cutter!

people report blown fuses and all sorts of craziness if this happens. so be prepared.

Pre owner cut radio wires(help is here!!)

Ok the previous owner of my 156 cut the wires to the stereo when i bought and left me with no clue how to rewire it to my radio,

But with some very helpful suggestions from you at AO i hooked it back up, no more going to work in silence!!! And country road driving with alfa speed, steering, and good music, NICE!!

I had to go to a junk yard and cut off the connections and take them home, so to save you the hassle try this.

You should have an iso connecter thats labelled buy one in a motor facters 5 quid should do it.

My car is an alfa 156 98' 2.0l so i can only say i works for this model.



Anyway here it is youll need:

1. a multimeter
2. an iso radio connecter (plus radio)
3. Some basic tools ie. snips,phase tester........



Firstly there shold be two RED wires and 1 black, find them.
OK now get your multimeter set it to the 2nd lowest voltage it will go and direct current,
should be 20V.

ok now place the black cord (multimeter) against the black wire,
and the red cord against both red wires seperatly and record the voltage.

1 red wire should be lower in voltage than the other red wire thats the IGNITION/SWITCHED
2nd red wire should be higher in voltage thats the BATTERY/CONSTANT
Black wire is GROUND/CHASSIS

RED/GREEN = ANTENNA POWER
YELLOW/BLACK = DASH ILLUMINATION

BLUE/BLACK = FRONT LEFT +
GRAY = FRONT LEFT -
ORANGE =FRONT RIGHT +
WHITE/BLACK = FRONT RIGHT -
BLUE/YELLOW = REAR LEFT +
BLUE/ WHITE = REAR LEFT -
WHITE/RED =REAR RIGHT +
BLUE/RED = REAR RIGHT -

OK there should be 2 wires left over. do not hook them up to anything.
i dont know what their for so dont do it.

hope this saves a lot of painstaking searching that it cost me.

Good luck!!!!!!!!

:thumbs: good post, although I'm a bit dubious about the voltage values you've posted ... did you have your multimeter on the "AC" voltage setting rather than DC?
