Sorry its been a long time since I fitted a stereo. I bought this car without any stereo so need to fit one so pulled out the wiring. Is this what you would expect to see or will I need to adapt anything to fit any modern cd player. As you can see there is a plug and three or four bare wires.

Thanks all

It will depend on the stereo you fit because the ISO wire harness maybe different to the one you have?

The black connector is a standard ISO radio power connector (speakers should be on a second similar but not identical connector). The red wire should be the ignition switched live, the brown wire should be the ground, the grey wire should be the illumination feed, the brown & red wire should be the permanent 12v feed (memory back up). I suspect that the other two pairs of wires go to the speakers. Most likely red/brown rh speaker +, red rh speaker -, blue/brown lh speaker +, blue lh speaker -.

It shouldn't make any difference, that is a standard ISO connector.

I agree the connector may be but the vehicle wiring won't be, for example if I were to follow what you wrote above it wouldn't work in mine because the colours are different, not all colour codes for sound systems are the same, this is why I asked.

Having previously worked in car audio and seen just about everything there is I'll bet you that one is!! The red and brown cables are of a significantly heavier gauge than the other two so will be power. Therefore it follows that the other two thinner cables will most likely comply with standard ISO wiring. It has a Herschmann radio aerial connector so its most likely European. Looking at the dash layout I'd guess its a Peugeot (but may be a BMW).

Its a VW Polo :Wky:

I think what Tech support was saying just because it has a standard ISO it does not mean its wired correctly?

The wiring looks pretty bodged to me and and converted over from vw plugs and the previous owner may not have got a stereo working and those wires may not even be wired to the correct pins of the ISO ?

Without actually being able to see it in front of you who knows?

In some senses the previous owner would of been better using a conversion harness then you cant go far wrong :W:

Admin your right in what you say just as is Father Tiresias but! the way I'm reading what's being suggested here is that there is some sort of universal colour coding for ICE in all make of cars which simply isn't the case. Ideally the way to make a concrete decision is as already said 'Time to get the multi meter out' Thumb

That confirms the colours then. German cars have used a standard colour code for power connectors since the eighties. The gauge of the cable confirms this too. On some later German cars the constant power feed and the switched power feed are reversed but the gauge of the cable and the colour code would make this obvious.

The biggest variations in colour coding are with Japanese cars. They were late in on the act and made their own rules up completely ignoring the standard set by Robert Bosch in the eighties. Speakers are on the ISO (B) connector which is usually brown in colour, and the cables do often vary in colour coding.

There should be some more wires buried in there somewhere. Standard VW speaker wiring colours suggest that those we can see are

Red - Front right speaker (+)
Brown/Red - Front right speaker (-)

Blue - Rear right speaker (+)
Brown/Blue - Rear right speaker (-)

There should also be:

Blue/White - Front left speaker (+)
Brown/White - Front left speaker (-)

Red/Green - Rear left speaker (+)
Brown/Green - Rear left speaker (-)

I think that you are right TS there are some subtle differences over the years regardless to which company it is. As for The standard that Robert Bosch set in the eighties I don't know how he did this since he died well before the eighties Speak no evil I can't believe that anyone even in this day and age would assume that the motor industry uses a standard color code?

Here is something that might help. I think what's being discussed here has been good but I do think that before any of us post such important info we need to either have a source that can be looked at or the person posting should adamantly say this is correct and be prepared to back it up, after all it only takes one wire to be wrong and there could be a fire? Anyway these are just my thoughts. :Wky:
