Accessory connector from Canbus system: which wire does what?

Hi folks,

I was into the dealership for my first 600 mile maintenance last Tuesday, and I ordered a specific accessory plug for feeding my Garmin 276C GPS. There are 2 accessory outlets on the Canbus system that allow one to drain power: 1 in the front, under the tank panel that hides the battery (it is zip tied to a framepart, and has a rubber cover on it), and 1 in the back under the seat (which I wasn't able to locate yet up until now).

There are 3 wires on the accessory outlet: 1 with a brown wire (must be ground), 1 with a red-and-white wire (should be +12V), and thirdly 1 with a I think blue-and-another-color wire. Does anybody know the function of this wire? The dealer tech couldn't answer very definitive, he thought it was a wire to power instrument lighting or the like, but he was not sure at all. He indicated however that the +12V would stay on for 15 to 30 seconds after the ignition was turned off.
As a complement let me tell you that the brown and red-and-white wire are positioned in the connector side by side, whereas the third wire is positioned on top of the connector between the 2 other wires, if that helps.

Rather than do the guessing, I would like to rely on the wisdom of this forum to find out the function of the third wire? Does anybody know?

I will receive my accessory connector tomorrow in the snailmail, so would appreciate knowing how to wire it to my Garmin 276C power cable.

Thx

Cool, keep us posted :thumb

I found it and it would be ideal for my tank bag as well. I will send a note to my dealer tomorrow and see if I can get any info on it.

Thanks,

Phil

Brown = ground

Red white = +12 V (stay on for +20 seconds after ignition turned off)

Blue/green = 12 V (follow the ignition key immediately)

I'm a little slow, and a "picture is worth a thousand words!" Is it possible you could take a picture of the connnector. I'll dig around and see if I can find the connector, but that is exactly what I'm looking for. Especially up there where I put my autocom and want all my toher stuff to run off of a relay!

Thanks

It will be a while before I take the covers off, but basically, if you take the battery cover off, you will see a metal cross member that is in front of the batter. If you run your fingers along the front edge of the cross member, will feel the cable and connector wire tied there. We believe it is used to power the BMW Navigator, but basically, it's a low current switched power circuit that you could use for your tank bag, GPS or whatever.

Hi guys,

Here we are with some pictures.

First of all the actual connector that you can order at your dealer. BMW Partnumber is 90 000 611 656

Then a few shots of the accessory outlet under the battery cover (rubber cover removed):

Anders indicated that the blue/green wire is +12V immediately after the ignition key is switched on and dies off when the ignition key is off. Well, yes and no: it is indeed switched directly with the ignition key, but has 11.2 V, which is 1.2 V less than the red/white wire, that gives 12.4 V, at least when the engine is not running! If the engine is running, the blue/green gives 13.2 V and the red/white gives 14.3 V, the brown wire being the ground wire. This difference could be important with some specific devices, so use in function of what you want to hook up.

For clarity sake: the terminals are numbered 1, 2 and 3 on both the connector and the accesory plug. 1 is the brown wire and is the ground, blue/green is terminal 2 (directly switched 12V on and off) and red/white is terminal 3 (directly switched 12V on and delayed by 1 minute 12 V switched off).

On the accessory plug the (yellow) wires are also numbered 1, 2 and 3 (see picture), in accordance with the terminal numbers, and are about 38 cm (15") long.

There is room enough between the battery and the frame to tuck away neatly the accessory connector together with the accessory socket. I read somewhere that the accessory socket allows to draw up to 7 amperes of current, sure enough for all the dashboard gizmos, like GPS, XM radio, radar detectors, walkmans, MP3 players and the like. But most likely not enough to add a heated vest over there.

I will now trim the yellow wires and solder them to my Garmin GPSMAP 276C power cable via terminals 1 and 3, because that will give me the time to push one of my 276C buttons, so that the GPS can stay on and continue on battery power, when I do a stop and want the GPS staying on, finishing the project off with some heat shrink tubing. The power cable will be fixed with some tie zips to the frame in order not to overstress the soldered cable.

Hope this helps out the guys that are interested and clarifies a bit.

Luc, you da man! I'm on this one, thanks for the part number. If you are ever over here, I'm buying :bowdown :beer:
Hi Phil,

My pleasure to add something to the common wisdom.

And BTW, you could see me coming since we have an office in Reston, VA, that I visit normally once a year. So I will have to hold you to that beer...

Luc,
Thanks a lot for your post & pics! They are of super value!
I ordered a mounting "small piece of plastic" for EUR 21,- today. That's fine. At least one thing is cheaper than in the US. :))
But the connector is a nightmare! Two BMW dealers told me the same - there is NO part number 90 000 611 656 in the program. No for the cars neither for the bikes. The latest ETK version ends with group 71 - that's all. They promised me to enquire BMW Rusland Trading tomorrow. Hope it will help.

Our parts guy confirmed that the 9000 part number does not exist in the US. Makes me wonder what our plug looks like.
I know my dealer had to ask twice, since he got originally the wrong connector delivered!

And that one started with 71, but doesn't fit! He had in his parts manual a note besides the 71 partnumber, written by hand, with the earlier posted 90 number, it was also on the package I got, and to make everything watertight, here is a pic of the plastic envelope the connector was in, so you can show it to your dealer to prove it exists.

'Originele onderdelen' is Dutch for Genuine parts....

Of course I anticipated on this and examined the connector before installing it: it proves to be a connector manufactured by AMP, and it carries the product code 2-967082-1. The connector was packaged in a seperate plastic zipbag and mentioned 'special tool BMW 61 1 656', coming from the German company Cartool out of Ingolstadt. But I reckon they source it from AMP. Interestingly the accessory outlet on the bike is manufactured by Tyco, a US company. Didn't note that product code down tough...

With all these info, how can BMW deny they have it? Beats me!

BTW: the project with the Garmin power cable, soldered to the connector worked out flawlessly: I strapped the connector to the ground cable of the battery, on the right side of the bike, where there is plenty of space to tuck it away. I routed the Garmin cable up under the wire clamp on the right side of the steering handle: looks like it is factory installed!

Thanks Luc, I will try to crossref the part number and see if it's available directly. Tyco bought out AMP and is now the parent company.

I'll see if I can shed a little light on the connector. The connector number is X9349, for optional accessories. The connector has three wires:

(1) Brown = ground
(2) Blue/Green = Speed Pulse
(3) Red/White = 12V

The Blue/Green is a pulse derived from the speedometer pulse and very likely will measure around 12V when the bike is stationary. When the bike is moving this lead will have a pulse whose rate will reflect the speed of the motorcycle (each pulse a specific distance and the pulse rate relative to speed). This connector was first introduced on the 2005 K1200LT. This connector is also on the R1200RT, The K1200S and the K1200R. It is the connector used for the BMW Navigator GPS kit. I suspect the speed pulse is for future use with GPS units that employ dead reckoning like the Garmin 2650.

The Red/White lead is ignition switched 12V with a retained power feature. The duration of the retained power seems to vary with the amount of time the ignition is on. Since this supply is straight from the ZFE (central chassis electronics module) it will be current limited. I have no direct information as to what the designed current is, but I am operating an XM radio and a GPS off of it on my K1200S without any problems. I will also soon be adding an autocom to this circuit and will be duplicating this setup on my GT. If you exceed the current capacity of the ZFE on this lead you could always use this output to drive a relay supplied by a fused connection directly to the battery.


Hope this helps.

Hi Randy,

At last the correct info! Thx a lot for this clarification.

The rated output seems to be 7A for the accessory outlet...

+1 Thanks Randy!

Now for the next, I tried cross ref'ing the connector at Digikey, Newark and Tyco, I will keep on searching.

Is it the number shown on electric schematic? And how to order the plug for this socket? My dealer does not have a ref number no price for this item.
That is the connector callout on the electrical schematic. I am not sure how to order a connector yet. I am hoping the efforts from others in this thread will bear fruit. For my S I used a connector I found in a pile of old motorcycle wiring I had.

It is the white connector in the above image. I will need another for my GT.

My dealer informed me that he had got a written reply from BMW Rusland today - there was NO such part number available for sale in Russia. BMW does not sell parts of the accessory kits.
Well I knew that there was a difference between our countries but did not imagine that there were different BMWs.

Phil,

Reviewing my pictures at the start of this thread, I noticed you can read the Tyco accessory outlet plug partnumber on the picture: it is 2-1452050-1. Maybe this helps too in the crossreferencing: you need the other connector that fits this one....

My local dealer (Fort Myers, Florida, USA) says the BMW part number is 83300413585
(For easier reading 83 300 413 585 )

I've ordered one, we'll see what I get :confused:

I have no idea why the number would change, but ....... (possibly an automobile part?) :confused:

I'll follow up as soon as I receive whatever that item is (hope its correct)
