I tried upgrading my rather worn 2011 XF seats with really nice sport seats from a 2013 XJ (X351). I was told they would fit from the guy I got them from.

They indeed perfectly fit into the car and look awesome however the wiring connectors do not fit, at least 2 out of the 3 connectors are different.

My original heated seats do not have the seat module under the seats but the new ones do.
The main seat connector (I call it "A") carries the three B+ power lines and ground wires (which then also go to the seat module connector that I call "1") and I think I just need to rewire a bit.

I would really appreciate if someone could look at the attached explanations with pictures I took and try to give some advice.

Here is a description of my wiring problem for seat exchange. More info in other files...

Send me please your VIN.

 

my VIN is: SAJAA0536BNS10842

 

So you have factory installed classic seats 8 way w/o memory function, give me 10-15 minutes I'll post part numbers what you need

Please check on memory seats modules (black modules under seats) could be VIN of donor car or description how many settings they have and from what MY they are

 

Great, thanks. I am at work now so cannot look at seat information. Here is a picture in case info clear for you.

 

So you got the climate seats, in this case you need additionally find the climate seats module, solve wiring and reprogram CCF for activating climate seats function.

Also you'll need find another one driver door card with memory button in case if you want to use memory seat module for saving and recall driver seat and steering wheel position.

 

I think for you the better way to order next connector housing to install them in XJ new seats instead of factory fitted for corresponding with factory installed harness, according to your photos:

Housing A: YPC912070
Housing B: YPC900630
Housing C: YPC901410

 

Thanks for the info. I do not wish to install the climate function at the moment (maybe later) as appears a lot of work from the information on your posts about this retrofit. I may get back to you about this in the future.

Regarding the memory function, I have already bought a memory with Botton for the door (2 memory settings). I think I will cut a hole and place it above the mirror switches if the cables reach there from within the door.

Did you have a look at the wiring pictures to see if I made the correct assumptions for re-wiring?
I was thinking the easiest would be for me to simply cut off the A and B connectors form my old seats and splice onto new seats. I just need to be sure it will work before doing this rather extreme measure.

 

In this case you haven't the heated function until you install the climate control module.

You could find the driver door with podium for memory switch in any bad condition for bargain price and just take out it, as I was made it before

I saw your diagrams, in any case you'll need to re-pin new connector housing according wiring diagrams X250 2011MY

 

Ah, OK, I did not realise that I needed the additional climate control on floor to work the heated seats as well. I thought this was only for climate control.
Winter is finishing so I can wait a bit and then do the whole climate box thing with re-wiring and update. Would I have to go to Jaguar to get the update CCF or can I do this myself with a OBD connector and laptop?

And thanks for the order Nr. for connector parts (can only get them from US after quick search but I am sure I can get from UK or even Germany).
Does any of the wiring control the airbag function? I want to avoid making it blow while I am working on it!

 

Unfortunately the JLR dealers doesn't want to make such kind programming,
I hope it possible to be done in future by me, if you find necessary stuff or someone who already have it.

Keep calm and change seats without any problems, for your quietness you can disconnect battery before seat changes

 

Thanks again for your help and encouragement, I will do this step by step.

I have ordered the harnesses (I of course forgot to order 2 of each! - I presume passenger seat uses same connectors) so will look very carefully at where all the wires from the seat should do to connect properly with the 3 car sockets.

Is this the correct climate seat module I need: JAGUAR XF Typ X250 Steuergerät Sitzheizung Sitzbelüftung 8X23-14B663-AF | eBay
If so I will get it and try to do this when I anyway do the rest. Do I need to order other harnesses to connect this box to car?

I will buy an old PC laptop (I have Mac) and install SDD software and try to do the CCF update myself. I saw there are some threads about this so I will refer to them.

I really appreciate the efforts everyone makes here on this forum and I hope that I will be able to contribute myself once I am up to speed.

 

Yes this module is that you need, for this module you'll need to order connector housings additional, but the best way find junk yard and cut off necessary housings with pigtails wiring.

If you have MacOS, you could install Parallels software and install Win7 32bit OS on it.

I think mine Mongoose cable should be free on second part of June, I'll try ask one man send it to you.

 

I do not know any junkyards here unfortunately. Do you have the original part numbers for the connector housings I will need?

Yes, that is true but I am not a fan of parallels. I could install Bootcamp and Win7.

Do you mean the ODB2 cable to the computer? Would you really be willing to organise sending one to me? That would be great!

 

Yes I have necessary part numbers for connector housings. The main problems not in connector housings, the problem with pin connectors. If you haven't junk yards near from you, try visit JLR dealer for asking possibility to sell you some spare wirings with pig tails from their SPX repair kit

 

OK, I have spent a bit of time to try and get climate control, module connectors from damaged cars without success and the dealers I contacted would only sell me the entire wiring loom of car for 400 Euro! I don't think so!
I will try to find a solution as you suggested with the SPX repair kit however my knowledge of this is limited. I will do some research.

I will nevertheless go ahead now and connect the new seats as soon as the new harnesses arrive for them. Could you confirm the following plan:

For connector A:

To get all motor and pump function:
Bu/R wire from car --> Y/R wire in seat
Gr/R wire from car --> Br/R wire in seat
W/R wire from car --> Bu/R wire (lumbar and bolster pumps)

There are also 4 thick ground (Black) wires in car connector and only 2 thick and one thinner ground wire in seat connector. Should I just match the positions of the 3? The fourth position in seat connector is purple-orange instead of black. I guess I should leave this.

In addition, I will not connect the purple/Green (VT-GR) wire from car as this is for the heating element power of the old seats, which will not work with the new seats because that will apparently be controlled by the climate control module (when I eventually do this).

Memory function:
I would however also like to fit the memory switch in the door now and I am not sure which additional wires from the 2 additional seat connectors I need to connect to the corresponding car connectors (connectors B and C).

In car connector B there are 4 wires: brown-green, blue-brown, grey-yellow, green-blue and new seat connectors also have 4 but only with 3 the same colour (grey-yellow, brown-green, blue-brown) and one different (yellow-orange instead of green-blue). Also in different positions. Should I match the colours where I can?

Connector C is more complex as there are 9 wires from the car and 14 in the new seat.

Any ideas which ones I need to connect?

Sorry but I am puzzled by this and cannot really understand the wiring diagrams too well as they do not give a clear impression of WHERE the different colours wires should go. Same for climate seat module!

Here is another set of pics of the corresponding car and seat connectors.

 

quick update on my seat retrofit project.

As I am still waiting to receive the new connector harnesses for attaching to my new seats, I decided to install the memory switch I bought on eBay into the drivers door.

Considering I did not have the original housing for the switch at the bottom of the door I decided to place it above the mirror switches, which is anyway a more practical position for it to be in my opinion. The length of the wire is just long enough for the existing car connector to reach up there and there is just enough space from the speaker for the back of the switch to fit - as long as you cut the hole near the top of the available space - see pics.

After removing the door panel and connectors https://www.jaguarforums.com/forum/x...es-how-110947/, I cut out a 30 x 46 mm rectangle hole using a drill and my very sharp pocket knife. After a little reshaping to get exact fit I inserted the switch housing so that it clipped into place. I then inserted the switch itself and put the door back on.

Pictures attached in case anyone ever wants to do this. I think it actually looks better than the original position for the memory switch.




drill holes at corners of 30 x 46 mm rectangle and cut out with small, sharp knife. I cut from behind to avoid potentially damaging the plastic.



Inserted the housing of the switch into the hole, after making a few adjustments to the shape.



Inserted the switch into the housing



View of the installed switch from behind the door panel



The wire for connecting to the memory switch (hanging down) is just long enough to reach the position at the top left of the speaker as viewed here.



Install door panel and ready to memorise. Actually will have to wait for my harnesses to arrive before I can install my memory seats and test.

 

Harnesses for the new seats arrived today, which should allow me to connect with car sockets.

I first decided to test only the seat movement motors and lumber/bolster pump functions in car, so I exchanged wires in seat Socket A only.

As pictures below show, I first removed the 3 black ground wires from original seat connector and placed them in the new one, then the 3 power lines with colours yellow/red, brown/red and blue/red (as outlined in post 1 above).




new harness for connector A at bottom, with the 3 ground wires exchanged in same positions.



view from the back of the new and original connector A harnesses



now the new harness with the 3 power (B+) wires also transferred



just kept the original harness attached to seat with the remaining 5 wires that I did not attempt to transfer



these are the 5 wires remaining in the original harness

I removed the old seat and inserted the new seats and connected socket A of car to new seat harness.

Unfortunately, the results were kind of strange:

Although all seat movement could be activated, the movements were not continuous and only short bursts of motor activity could be achieved by sliding/pressing the switch-pack levers. I had to continuously release the lever and slide/press again for the next short movement to happen. Moving the seat all the way back or forward required about 20 such independent actions! Same for moving seat up/dowm and tilting seat back/forward.

It is as if the motor is not getting enough power for prolonged periods and simply stops after about one second. The lumber and bolster pumps however seemed to function OK, without stopping after about a second of holding the lever in the appropriate position. The car battery was OK I think as could start the engine without problems.

Any ideas as to why this is happening. Have I missed a ground wire somewhere or do I need to connect some of the other wires from connectors A, C and C as well?

I put the original seat back as I anyway will have to figure out which wires I need to connect for the seat belt alarm and the seat position sensor that controls the airbag inflation rate.

This is all very puzzling and I will have to take some time out to look into this.

Any suggestions would of course be most welcome. 08292, any ideas? did you also have such issues?

 

I could help you only in the end of week. In the missing pins from your factory installed harness which must be connected with present new seats harness pins are the wiring for climate seats function.

 

yes, I basically understand that some wires coming from the climate control module attached to the bottom of the car will have to be connected to the seat connectors (when I will install it...). However this will only be for the heating and cooling functions, as far as I understand.

My current problem is that, in addition to allowing basic motor movement for seat positioning (connector A), I would need to connect wires for the following features:

1. seat belt engagement warning

2. seat positioning sensor that sets air bag inflation rate

3. memory switch function

For the above 3 points I am not sure which exact wires to connect.

The other problem, as mentioned in my last post, is the fact that the seat motors are not functioning properly when I operate the switch-pack levers on the side of the seat- seats move in short bursts rather than continuously.
I thought this was because I just needed to connect some other wires. Apparently, it could be that I need to reprogram the seat modules (according to thermo form another thread). That means I will need to get SDD up and running sooner rather than later and get access to an appropriate OBD-to-USB cable to connect car and computer. Looks like I should use a dedicated, freshly installed Win7 32 bit laptop for installing the SDD 149 version. I will follow the instructions listed here together with the softwareIndex of /265935/idscentral

This is another topic, but, after glancing at this threadhttps://www.jaguarforums.com/forum/g...-%2A%2A-33347/ to be honest I fail to understand the complexity of discussions about using the correct OBDII-USB (car-computer) connector for successfully running the SDD software. I of course appreciate that it is indeed a complex topic and cheap cables can be problematic, however why should the physical quality of such connections be so crucially important for allowing particular programming functions of the software to function with the car?
