:1zhelp:

Last dude snipped the Audio wires from my '02 Passat and I have bought a Blaupunkt Unit and the Blaupunkt adapter wires.

What would the best way to go about hooking it up in your opinion ?

Match up the wires with a wiring diagram / and crimp the wires ?

or take out the remaing wires where it connects into car and buy a new loom or whatever this is called ?

Also - where do these wires go to and how would you get at them - under steering wheel / through glovebox etc ?


This is what i have for the wiring diagram

A Right Rear Speaker (+) Blue Purple
B Right Rear Speaker (-) Tan w/ Blue Stripe Purple w/ Black Stripe
C Right Front Speaker (+) Red Gray
D Right Front Speaker (-) Tan w/ Red Stripe Gray w/ Black Stripe
E Left Front Speaker (+) Blue w/ White Stripe White
F Left Front Speaker (-) Tan w/ White Stripe White w/ Black Stripe\
G Left Rear Speaker (+) Red w/ Green Stripe Green
H Left Rear Speaker (-) Tan w/ Green Stripe Green w/ Black Stripe
I Do Not Use
J Do Not Use
K VW Amp Turn On Wire - Connect To New Radios Blue Power Antenna Wire
L +12 Volt Ignition Wire Yellow w/ Red Stripe Red
M Power Antenna Turn On Wire - Connect To New Radios Blue Power Antenna Wire
N Dash Light Dimmer Wire Gray w/ Blue Stripe check for availability
O +12 Volt Battery Wire Thick Red w/ White Stripe Yellow
P Ground Wire Thick Tan Wire Black

thanks in advance

Ouch - wiring headache!

I'd use the diagram in the rear of a Haynes manual (or better if you can find one) and work out what is what and then, when I'm sure (that part alone would take me a week!) use solder and heatshrink.

Depending on your confidence levels you may want to hand it over to an electrical specialist.

The wiring goes out the back of the radio cage and then, depending on which side of the car it goes off behind the lower dash or glovebox. You can get to and see the wires by removing a few torx screws. The wiring is all wrapped in black tape/felt.

I found this wiring diagram from a VW manual for the passat that I found online.

There is another diagram for an audio system which has a separate amplifier fitted in the left handside of the boot. Let me know if this is what you have and I'll post it too.

From what I remember all the stereo wires are in a loom, wrapped in the black felt. Has the last guy simply cut off the old wiring harness? and left you with a bunch of wires still in the old loom? Or are they all over the shop? U should be able to buy the ISO adaptor for your stereo, and then simply match up the wiring from your stereo, to the descriptions you had in the first post.. Snip off the Car side connector, Then solder and sleeve or crip the two halves together. :biglaugh:

Hi Sherlock ,

thanks for info - yes wires are still in a loom but not long enough to work with / crimp without taking out

have the ISO adapter ok so think best bet will be to remove from Car connection which will be a job and a half in itself i reckon

Hi Mate.

The one way you can test what Wire is for what speaker is too use a PP3 ( square Battery) touch the Two wires on the battery and you will ger a "Crackle" on the speaker it relates too. :)

The Power should be

Red - Perm Live
Green/Yellow - Ign Live
Black - Negative
Blue - Electric Ariel ( if applicable )


Id solder the wires backtogther and tape them.

If your strugling ill wip the radio out and get a pix

thanks Andy ,

Had those little insulated joints that you crimp but couldn't get crimping properly with confined space. Then I struggled all day trying to take dash apart to try and get the loom out to work on but discovered it shared a heavily taped section further back with wires that go down to left hand side of gear stick ( previous phone kit ? )

So scrapped that Idea and went to a local garage who usually have an audio electrical specialist around but not today .

however I picked up one of those plastic wire connectors with 13 openings on either side and screws to fasten the wires . This did the trick -

The next nightmare was working of 3 different wiring diagrams I have for Passats and the best I could manage was 3 Speakers working with the Left Front not playing ball whatsoever.

I may have to try that trick you gave to see if I can hear a crackle from it otherwise the door panel will have to come of for further inspection.

oh the Joys - but was damn satisfying when I heard the 3 Speakers in all their glory

Hope to have some pics shortly / may go with your soldering suggestion as the current setup is not the tidiest - will have to draft in my Father for that though - the passat cockpit not best place to learn new soldering skills

New skills learnt today were stripping Audio Dash Trim and reckon I have it down to about 5 mins:D

Pitfalls were slicing top of thumb with Stanley Blade :aargh4:

If i could only have 5 mins in a dark room with guy who snipped the wires :smashfrea

HI Folks

can I just dig this thread up again, and ask on a VW Passat 03/04 model, the green/yellow wire on the black ISO block should be the ignition live.

I have metered it and it drops from12v down to around 2 or less when i turn the keys off

Just, Im having some trouble getting an ignition live powered conneects two adaptor working on this particular car, and thats the wire I took the ignition feed from

just wanted a second opinion that it was (or is) the right wire

thanks

The wiring loom colours are; Ignition feed RED, Live feed RED/BLUE. Can you work to the iso connector from that.

I can't find a green/yellow wire on the vw wire diagram. I'm only looking at the wireing loom diagram. An iso connector might have different colours. Has your car got the seperate amp cos that gives extra wires as does the dash display if you have it.
