Thanks for the larger, clearer pictures Dougie. Although the third picture is out of focus I have deduced that the missing socket appears to be no. 4 which is the left rear loudspeaker signal.

As I see it, if you use that 13 pin connector you will need to install conductors in the empty sockets for the following: Pin 4 NSR speaker signal Pin 7 K-bus Pin 10 Steering wheel switches +ve Pin 17 Steering wheel switches -ve Any help? Simon

Well, I cross-referenced the pin numbers and their physical arrangement in your photos with the diagram of that connector in RAVE. That reveals that the empty slot is no. 4. You can clearly see "4" next to it in your first photograph. Simon

OK Dougie. There are four missing connections and we will need to work out which wire goes where! Here's the answer:
On your Carav diagram there are four empty cavities: next to 8, next to 9, next to 11 and between 10 & 12. The steering wheel controls -ve connection (RAVE pin 17) belongs next to 8. The NSR speaker signal (RAVE pin 4) belongs next to 9. The K-bus (RAVE pin 7) belongs next to 11 (I've discovered that the K-bus controls the CD changer). The steering wheel controls +ve (RAVE pin 10) belongs between 10 & 12. I'd like to know why your apparently original factory 17 pin connector has one of the NSR speaker connections missing. Quote:
I'm further confused by the first thumbnail photo in your post no. 1. Are these in the car with the VDO radio unit? These three connectors also correspond with a Symphony installation (according to RAVE) except that the yellow/green/blue assembly you've later shown with only two wires attached. Simon

The adapter arrived today. I connected it to the ISO harness and everything worked including all four speakers but not the SWC obviously. The new recipient car (had the VDO, now has the ISO wiring with the new adapter) has the C-type blue/green/yellow connectors as shown. Only the green is wired, and I understood Rave to show they came from the SWC. These wires appear to me to be green/orange and green/purple although I have unreliable colour vision when it comes to nuances. Here’s another pic of the connector which I’ve removed. I’ve no spare ferrules yet for the new plug but I did connect both ex-green-connector wires next to pin 8 and between pins 10 & 12 which is what we both agree are what the Harmony needs for the SWCs. It did not work. Dougie.

Hi Dougie,
I've sent you a PM asking if you can educate me with some basic facts about what you're doing because it's getting very complicated, well to my mind it is anyway! Quote:
Thanks for the photo but it's no use because it's a thumbnail. They're low resolution and can't be enlarged as I said earlier. Simon

Well guess what. It works! ��
Thanks to Simon (SD1too) and Ray (raykay), we narrowed it down to the two Green/Orange and Green/Purple SWC wires looking like they should be connected to the missing pins 10 & 17 in the new BMW adapter connector. I did try that a couple of days ago but didn't work. Having reflected though, I considered I may either have connected them just one way round and not tried the second permutation, or perhaps the wires hadn't been pushed in firmly enough through the back of the connector into the blank hole where the male pins on the radio lurked. I set about it more scientifically this afternoon trying both permutations and making sure the connections were firm, and - all SWCs now work. I'm all made up. So for anyone wanting to install a Harmony with the BMW connector into a car with a VDO CD413X and ISO connectors, the SWC wires (as discussed above) are G/O and G/P connected to the small green ISO connector which must be cut off - or perhaps use a male mini-ISO adapter to plug into the green connector to preserve it - and the two wires extended. The G/O wire goes to pin 10 on the BMW connector and the G/P wire goes to pin 17. They must be that way round. Those positions are blank holes and have no female pins installed, so you need to address that. I used a small round 3mm plastic rod, cut two pieces so each pushed down inside each hole but still protruding about 4mm so they can be removed, which tightly held the wires in contact with the male pins 10 and 17 on the radio. I'm sure I could have sourced the correct female pins in time but I'm happy on this occasion to bodge it as it's secure and safe. If you have other permutations of radios to fit or swap, have a look at https://www.the75andztclub.co.uk/for...d.php?t=214040 which is a similar thread with raykay's input for the other radios. 8-year old thread, still relevant. Thanks again to everyone who contributed. The forum rocks.
