Pinouts for butchered stereo ISO connector

[Syncros]

Would anybody happen to know whether there are any pin/wiring diagrams for the stock stereo ISO 'A' block attached to the standard loom? Mines been cut and although i can identify most of the cables there are 3 or 4 which i'm not sure about.

My understanding is (as i have the JBL amp), one of the wires is the remote for the amp located in the boot, powering the app up when a current is detected? If i remember rightly (from memory) there is a mauve, yellow/green, 3 white, a red and another 2. A total of 8 wires.

I've identified the constant, ignition, illumination and earth wires although i'm unsure about the others. It'd be good to get clarrification on each one. I've checked the Haynes circuit diagram but the coulors listed are inconsistant with what's on the car.

Thanks in advance and any help would be much appreciated!

Or, even if someone whom has the JBL amp setup could post a pic of their 'a' block, that'd be a step in the right direction

This could probably do with being moved to the ICE section

Is this a new member thing or does nobody really have any idea what the wires attached to this plug are?

Sorry mate, I'll change the topic title for you to get a few more bites. I don't have a 406 any more so I can't help you but you will get an answer from someone

It's not such an easy question to answer for a semi-mux D9, as both Haynes and the only other site I have access to feature fully-mux cars

If it's any help, the 8-pin black connector on later cars goes like this:-
1 = phone mute
2, 3, 4 = van network
5 - n/c
6 - ign +ve
7 - permanent +ve
8 - earth

The 8-pin white connector is for the speakers
1/2 right rear
3/4 right front + tweeter
5/6 left front + tweeter
7/9 left rear

Thanks fellas

After exhaustive testing I'm pretty sure i've identified a grand total of 3 wires! However, i'm testing using a stock radio which i'm now pretty confident, is faulty.. I'm sure i've found the ground, permanent live and ignition, although i cannot find the illumination wire.

So, in essence i have 4 or 5 (of a potential 7) wires i have no idea about. I say 4 or 5 because there appears to be 2 wires with a constant 12v. The other 3 include 1 wire of which has no voltage whatsoever (no matter what i turn on), 1 with a constant 1v and 1 with a constant 4.5v.

I'm confused that there appears to be 2 constant 12v wires running into the radio?! .

Unless the 2nd 12v is voltage for the stock JBL amp, which is outputted via another wire upon power up (which i doubt) or whether there is just an output to the amp from the radio acting as a remote?? The amp appears to be fused through the same circuit as the siren?

I'm sure one of the wires will be an output to the dash display but there is at least 1 (or two) more wires which make NO LOGICAL SENSE!

[Doggy]

I don't believe there is an illumination wire - it communicates with a remote display, which is used for other functions too, (clock, trip computer, warning messages). The van, (vehicle area network), bus connections probably account for the 2nd +12V and the odd voltages - it's vital you don't connect anything incorrectly to these.

[Syncros]

I'm totally lost in that case. There are 3 white wires attached to the loom, all identical , even if i did have a wiring diagram i'd not be able to tear them apart .

I need to find another semi-mux exec with a working stock stereo to attack with my multimeter

I've got the semi-mux on Sedre but it shows navigation & CD changer (or I can get one up with the amp as well)

Did you manage to find any numbers on the wires?

Btw there is mux to the radio...

[Syncros]

There are numbers on a few of the wires but they're difficult to make out, i'll try taking a closer look and writing them down. By the looks of things it's only towards the end of the cables that have been printed on (not all the way down the wires length). As the Haynes manual is referencing fully mux cars it also only lists 6 wires (and the colours referenced do not match). The only wire i can cross-reference with Haynes (according to number) is the earth (which i've already identified). One of the white cable appears to have something writtain on it but i'll have to see what i can make out and write them down.

Is there a semi mux wiring diagram anywhere?

[Doggy]

It's likley the haynes is a semi-mux version, (as Steve points out they're all mux as far as the head unit's concerned), but there see to be many different permutations of them. Mine only had 6 wires - originally there was nothing connected to the phone mute, I added that aftersome research, I think on the coupe club.

[steve_earwig]

From Sedre:
8 way black:
1
2 9004C - mux
3 9005C - mux
4 XE01C - BSI +ve (possibly mux - 3rd wire?)
5
6 AH25B - accessory +ve (fuse 25)
7 BH10A - battery live (fuse 10 & shunt)
8 M841- M is always earth

8 way white:
1 8470 : Right-hand rear loudspeaker + command
2 8471 : Right-hand rear loudspeaker - command
3 8422 : front RH tweeter + control /8430 : Right-hand front loudspeaker + command
4 8423 : front RH tweeter - control /8431 : Right-hand front loudspeaker - command
5 8410 : Left-hand front loudspeaker + command /8420 : front LH tweeter + control
6 8411 : Left-hand front loudspeaker - command /8421 : front LH tweeter - control
7 8450 : Left-hand rear loudspeaker + command
8 8451 : Left-hand rear loudspeaker - command

Thanks, Steve! What you posted is exactly whats on the Haynes diagram. Can you post the amp version?

I've some photos here which I'm hoping will help..

1st is a photo of ALL of the wires i have. The good news is, one of the white wires i've confirmed as permanent live from the fuse-box (the code on the wire also seems to match the circuit diagram), another one of the white wires i'm pretty sure is part of the VAN, although i can only make out 3 characters on the wire (01C), obviously this wires white and not red like Mr Haynes reports it should be. I think the full code for this wire "could" be XE01C?



So, remaining i have a red, a yellow and a white. 2 of these (the red and white) as far as i can tell have no identifiable marks on them what so ever. The yellow has this..



Which i cannot find on the Haynes circuit diagram! This could be the remote to the amp?

While rummaging, i also managed to find this..



Does anyone know what this is?

[Syncros]

Also, is it sensible to conclude that the radio will not power on unless connected to the van (and this 7th mysterious wire)? Even once i've identified the wires i still need to figure out the pin order on the plug
