Seat connector

Post by OXO »

I've managed to source some M Seats which are in a dire state, so that's my winter project.

First thing is to get the electrics sorted. The Seats are Pre facelift i belive as they have the 3 separate connectors.

I need to source the correct facelift seat side connector. Does anyone know the part number of this yellow connector.

The part number on the bag is for the push-in contacts.

If you have a look on realoem there is a section for connectors and the pins etc. I'd guess that if you looked up the part number for the pins you have, you'll find the connector on the same diagram.

The part number of the yellow connector is on the right hand side of the picture.
If you are looking for the other half of the plug then put this into real OEM

I got all the part numbers for the connector, but it's no help. None of them show up on realoem.

I think what I need is the complete seat cable with connector, like this 3 series one.


http://www.ebay.co.uk/itm/171137584580? ... 1438.l2649

I have searched realoem for the z3 equivalent part, but no luck.

Slightly tempted to just order one in the hope that it's similar enough to modify.

Unless someone here has a pair of facelift seat cable to sell?

Part 5 is your friend I think, it is a wiring loom repair kit that converts from old to new :wink:

I saw that and decided it was the chassi side, not the seat side because the connector looks wrong.

Are you sure?

I think I might have exactly opposite problem - I have pre-facelift car and I have bought seats from Z3M facelift.

Can anyone suggest which part number do I need to make it work together?

Fairly certain this is the correct part, Robert T has had a connector retrofitted, he maybe has a part number he could cross reference.

OXO, as I understand, you are in opposite position as me - you have facelifted car and want to fit pre-facelifted M seats. As I got from forum/links this part is for my situation (pre-facelift car with facelift seats), and you need exact opposite to this part.

Sounds like we need to do a wiring swap. Would you be interested?

This is the underside of my M Seats showing the connectors I need to change.

I might be interested. The only problem is that my M seats are still at customs (I hope to get them next week) and my z3 is at bmw dealership service where they are changing poli bushes and engine cylinder head and tons of other parts. So it can take a month or even more before I will get my car.

If we can do switch so that no wire needs to be cut, and you can wait, then we can do that. Otherwise I can just replace connectors from original seats or I will buy this adaptor part mentioned above.

Your connectors look the same as mines on original seats - I know because I did seat shift fix this summer for my original seats.

I can wait, as we aren't using the car in the winter.

But, I also want to make progress, so I will be trying to source the connector. I think I read that the cable conversion part is no longer available.

Keep in touch. We may be able to do something. Are you in the uk?

I had the same problem when I fitted my ///M seats, from memory the adaptor was the wrong way round for my purposes. I spent ages trying to source the part numbers for all the bits.

I have a similar query:

M seats and I have the black and white connectors as per your photo. But there is also a round yellow connector that connects at the back of the seat and the wires disappear up the back of the seat.

Anyone know what connector is? I have 1 set of seats with and another without....

I'll try get a pic this weekend.

Think that will be on the passenger seat for the seat occupancy sensor, drivers seat doesn't have one as they rightly assume someone would be in that seat if you crashed

Despite having a long email thread with Cooper BMW, we have failed at getting any part numbers for the connector or wiring.

So all that is left to do is to see if someone has facelift seat bases or wiring for sale.

I think the guess is that they are for the passenger seat occupancy sensor. I can't think of anything that the driver's side should have that the passenger side does not.

I'm sure looking at the shape of it it is the airbag sensor. Maybe the seats came from a coupe and the seat belt guides have been added retrospectively.

We are getting closer. Coopers have found the tensioner repair cable. 61 10 8 413 898

It has the yellow connector and a wire to the belt tensioner. :D

Need to find the other wires and contacts now.

Hi yes there was but I can't remember what it was and when I left dealer they chucked all the old useful information out. I think the Z3 one was the same as the E36 kit. It's been a long time since I sold

Hi OXO

You've pointed me in the right direction! Many thanks.

The yellow connector as per my pics is the seat belt tensioner. For some reason on the driver side it is that type of connector but on the passenger side it has a flat yellow connector (with 2 out of 4 pins).

Easy swap now!

Hi OXO,

This was driving me mad so out to the car with spanners in hand and my car now in bits this is what I found.

The connector under the seat is a modular connector, my connector houses the following: -
  • Seatbelt pre tensioner
    Heated seat loom
    Power seat loom
    Occupancy sensor loom
The yellow connector under the seat does have a part number on it but it is not recognised by either RealOEM or BMWFANS, however this yellow connector seems to be an integral part of the "repair cable - Belt tensioner" loom Part no: 8 413 898. Part 1 below.

I have take some pics below of all the connectors etc that I have, please note this was my passanger seat.

Are your seats pre or post facelift? The connectors on my seats are quite different.

I'm going to my garage to take pics!

Mine are pre-facelift then (which makes sense as it a 1999 car).

These are the connectors on the passenger side:

black and white connectors for power seats and heating
Image

Red connector for seat belt tensioner and white for occupancy sensor
Image

Driver side is the same except for the seat belt tensioner which is this cable and connector
Image
Image

Didn't realise there were several iterations of cable connectors.......

No problem OXO, With the pre tensioner cable being marked as a repair cable I wonder if it comes as a kit of parts with all the other connectors/terminals in the pack?
