WTB Power Seat Connector

[KevinH1990]

I managed to find a 12-way power seat in reasonably good condition at a fair price. In order to install it in the most reliable way possible, I'm looking for a connector. Here are a couple of pictures:





They may be in other parts of the car, but the most likely source would be the wiring harness from an 8 or 12-way power seat.

Please let me know if you can help me out.

Thanks,

You need the car side of the connection?

Yes - It should be in the harness under the driver's seat of a car with a 12-way or 8-way power seat.

Thanks

Subscribing since I need the seat side of this and I might learn something. Bought a pair seats yesterday and the connectors were cut off to use in an 997 seat conversion

The seller of my seats took them out of a 996TT to make a race car. Unfortunately he was a little rough with them and several pieces are missing. I'm not sure that I can save the passenger side. The leather is in great condition though.

I previously installed 8-way power seats in my Boxster. I posted instructions here:

The only difference with the 12-way driver's seat is one additional connector for the lumbar support.

Thanks that's very helpful information. I have existing seats in terrible cosmetic condition that are heated and memory and a set of nice memory seats (no heat) that had the wire connectors cut off. So with all of that inventory I am going to try to get one set of nice seats with memory and heat!

The most difficult part of the task will be taking the nice leather off of the non-heated seat pads and installing it on the heated pads. The leather is held on by hog rings and most people find that it takes time to develop skill with them. There are videos on YouTube and those should provide basic skills.

Woody had the part, so I'm good. Thanks for the replies.

Obligatory “holy thread resurrection, Batman”.

I spent hours (maybe even days?) looking for this connector from places like TE Connectivity, LEAR, etc on / off for the past couple of months but found that absolutely no one sells it online & the search seems to be made harder by the fact that this is a 2-part plug that clips together, so it really seemed impossible to find, though I did find a solution.

I did a 2-way to 8-way conversion & while switching the electric base onto my driver’s seat, I noticed that the backrest’s motor loom plugs directly into the memory seat CU & that it can also be disconnected from the motor itself, so I checked the PET diagrams for this loom... sure enough, you can purchase this one particular harness (99661254400) separately (sourced directly from Porsche for ~£20).

The backrest harness only has 4 of the 5 pins populated but I found that I could de-pin a similar gauge wire (with the smaller JPT pin) from a VW connector pigtail (1J0 937 733, Orange connector, Red/Green wire) and use this wire to populate the final, 5th pin. I did Google this afterwards though, and you should potentially just be able to buy a “000979225E” repair cable from VW & use that. If you're only replacing the connector, you should just be able to de-pin this & pin your original loom into the new connector.

The only issue I ran into with this was fitting the connector into the seat’s memory control unit: there’s a little ridge/notch on the connector to stop you from installing it into the wrong hole so I just nipped this off with a razorblade & it seated perfectly into the CU.

Hope this helps anyone having this problem in the future
