Swapped CD changer but plugs don't mate
 

To my surprise my "new" 02 Connoisseur Tourer has not got a glovebox CD, but my old 04 has. So I removed and installed it in the 02, thinking it would be a simple "plug & play." Silly me, why is life in RoverLand never simple? It's the same Harmony radio so why don't the plugs fit?
Someone please solve the solution.

I assume the female connector on the left is attached the to CD changer? And the male connector on the right is one found disconnected around the fuse board area? Are you certain the male connector is for the radio? The wire colours don't look correct.

Hello Dave,

It's rather complicated I'm afraid.

According to RAVE there will be differences depending upon whether the CD changer was factory-fitted or added as an accessory by the dealer. Apparently the CD changer was always an option, never standard.

Factory-fitted
An "overlay harness" is used. This has a 10 pin rectangular black connector (C1316) at the Harmony end. Only four terminals are wired and the colours are pink/black, yellow/black, black/pink and black/yellow. This connector fits into one of two rectangular ports on the 17 pin square-ish black connector (C1315) at the rear of the Harmony. Do you have this on your 2004 car?

At the CD changer end I have no physical details of the connector (C0941) but in addition to the wiring colours above there should also be black, white/red/yellow (K-bus) and purple/pink, so that's a total of seven connections.
Do you have these on one of the connectors you've photographed? I'm afraid I can't see clearly the number of terminals or the wiring colours from the thumbnail picture. Matt's photo is much better and may have the wiring colours I've given.

Dealer fitted
RAVE says "an additional link harness" was used which is "not covered by this manual".

Any help?

Simon

Most grateful to both of you. The CD changer (Alpine) has no connection into the back just the wires come out. Below are two more photos of the harness plug (top) and CD connector (below).

I can't see me being able to work this out - I'm OK on swabbing out EGRs - but auto electrics is beyond me, so whatever you suggest will probably mean a trip to a local expert if I can find one.

Cruise control?
 

This may well be a total red herring but copying the BMW number off the hanging down harness connector - which is very difficult to read, but could be 1-967-415-1 and Google that comes up surprisingly here: https://the75andztclub.co.uk/forum/showthread.php?t=632. This leads to a lengthy debate which may suggest it is a cruise control lead and nowt to do with the radio. What do you think?

Well done on finding the number. It does look like the cruise control connector.

The cruise control ecu is fitted behind the glovebox on my diesel and I had the connector but no cruise until I retro fitted it. Some aftermarket changer units had their own specific loom adapter and control box to fit a changer by Phillips or Sony if I remember correctly. Again, if I remember correctly not all cars had the standard changer plug fitted but my memory isn’t as good as it used to be.

According to RAVE the diesel has an "interface ECU" for cruise control situated "in the front passenger footwell area, behind the fascia". It has one 12 pin connector. Is your 2002 car the diesel?

But let's not get distracted! You're looking to mate your CD changer flying lead with a matching connector on the car's loom. You don't need any auto electrical knowledge to observe the wiring colours on the flying lead (from the CD changer) and see if they match the available connectors on the car's loom.

Dave, please can you post photos using the "mountains" icon rather than thumbnails which are small, low resolution and cannot be enlarged on my laptop. I'm happy to help but I need to be able to count the number of terminals on the connectors you're photographing so can you take the picture end-on to the terminals? If you can tell me the wiring colours as well by unravelling them and noting them down that would be extremely helpful.

Simon

If you dont already have the wiring in place, I think you need one of these: https://www.ebay.co.uk/itm/255265962...mis&media=COPY

It's hard to tell from the low quality photo, but the connector and wire colours appear to be correct. It will involve a bit of wiring though and finding the correct pins to crimp on the radio end could be tricky.

Right 02 plate is another diesel Tourer.
I always use the "mountains" icon - I didn't know there was any other, but that does raise a mystery. If I use my proper office PC - still running on XP, yes I know, I know - the pics come up enlarged. I always upload at 800px or 700 px, but if I look on my Dell laptop (Win 11 Pro) then sometimes they appear as thumbnails, sometimes full size. So the pics below I am going to upload again via my Dell.
And PS: I've run a R75 for some 11 years but never bothered with cruise control: it's so easy to drive (in auto) even long journeys to Burgundy or Barra I've just not bothered to fiddle.

Thanks very much Dave for the brilliant photo but it doesn't relate to anything in RAVE I'm afraid.

In the absence of someone with Harmony experience spotting your thread, I'd suggest searching the ICE sub-forum as I'm sure I've read about these mysterious overlay harnesses before.

Sorry not to be more help.

Harness VUL 100310?
 

I keep coming across this cable as necessary to connect a Harmony radio to the CD changer but I see various images which appear to plug in to the back of the CD rather than directly to the plug that I have. Any ideas please?


(https://the75andztclub.co.uk/forum/s...ight=VUL100310)

Simon/Matt: I must be losing my marbles. Having spent hours trawling the net for another cable/harness; peering at minute code nos. on BMW plugs that an ant would have trouble reading - I had a Eureka moment at 4.00am this morning. I've already a cable, in the old car. I just have to remove the Harmony, unplug the harness and reverse procedure in the "new" car. Can you see any snags?

PM sent re harness.:)

You might need to partially de-pin the connector that the radio end to transfer the wires over without cutting and crimping new terminals on. I'm not 100% on that though as I put a CD changer on a Symphony system which has different connectors.

De-pinning tool: https://www.ebay.co.uk/itm/165055891...mis&media=COPY

The tale continues . . .
 

I thought I had solved the problem by using the connecting cables from the old Tourer to the new. Silly me. Having taken the Harmony out I see the mass/mess of looms here. I had thought that there would be one simple direct loom (VUL 100310) that would connect from the back of the radio to the plug that lurks beneath the fuse box that connects to the CD. Below you can see that life is never that simple as it splits into the main harness.

However I have had a most welcome offer of this elusive loom which may or may not be the answer for a frustrated elderly gent.

Thanks for this Dave.
From your photo pink & black and yellow & black can be clearly seen from the small CD connector inserted into the main Harmony connector. I listed these wires in my post no. 3.
These wires must emerge from the loom somewhere near the CD changer as they carry the audio left and right channels. What we're seeing cannot be a dealer-fit accessory, the CD changer must have been factory-fitted.

What do you think Dave?

Simon: This is turning into an epic, things have moved on. A well known trader who is no longer a Forum member is sending me the harness VUL 100310 which he says should provide the vital Missing Link. I have pulled this out from posting here https://www.the75andztclub.co.uk/for...ad.php?t=88386. Unfortunately, and there always seems to be a downside with this, the posting lists the Alpine models, but of course mine (XQD 000470PUY) is not shown. So as usual I don't know, but will have a close look when it arrives. Fingers crossed as usual.

My harmony radio is in the cupboard and since I gave the cd changer away, the plug is still in the glovebox. Not sure it's removable as the setup is the same as yours 🤔

Thanks but I'll wait till I get this loom.

Another chapter on VUL 100310
 

Kevin at Bolton (Legatha) has kindly written me the following about fitting the vital extra loom (VUL 100310) as follows:


"VUL 100310 I obtained was an exact fit, I simply had to disconnect the big 17 pin BMW connector from the back of my Harmony radio, attach one end of the loom to the car-side connector, and the other to the radio - again these are big BMW 17 pin connectors.

The loom has two other connectors - one goes to the glovebox and connects to the CD changer and one goes to a small 10 pin outlet on the Harmony (it is built into the BMW 17 pin connector) - now here's where it gets interesting, I plugged mine in, the CD changer worked, i.e. it loaded and unloaded and appeared to play CDs, but no sound was forthcoming. More research led me to this post...

https://www.the75andztclub.co.uk/for...nger+blue+clip

So once I had modified the loom's small 10 pin connector (i.e. flipped it 180 degrees) which forms part of the BMW connector to the rear of the radio as advised in that post it was all OK."

Happy ending
 

To finally wrap up this saga Terry up at deepest Shropshire did fit the vital harness as mentioned above. There were yards of extra cabling to tuck in - it's a three arm harness with big connectors - but he managed it of course, far better than I could have done. Amazingly he produced a brand new harness in an unopened bag that he's stored for many years.
So now I can listen to my Duke and Ella as I waft along . . .
