    How to Disconnect Power Seat Wiring (Driver)

    I have a '95 XJS convertible, and as you may recall, I was attempting to work on the handbrake.

    A lot of my problem with successfully completing this project is my lack of access to the hand brake area due to the seat.

    I can't remove the seat as there is a ribbon cable from the floor of the vehicle to the Seat Motor Assembly (I assume).

    Does anyone have any suggestions on how to disconnect this cable and the strain reliefs so I can fully access the hand brake mechanism area?

    Thanks -

    Just in front of seat is a raised floor area that can removed. Two screws towards the pedal end, lift up carpet. Then unscrew ribbon white plastic holder, unplug ribbon from seat module. There maybe another plug for heated seats. But follow the wiring and easy to spot.
    But once floor area is removed, or before, you must unbolt back or front seat bolts before unplugging as you need to move seat to get to second pair of bolts.
    if you need more guidance let me know.

    Thanks, Tony -

    Maybe this weekend I'll give that a look. I agree with you that you have to move the seat forward and back to get access to all the bolts on the tracks.

    Thanks for the response.

    I think you will save yourself a lot of pain and bother by buying a tool that will fit between the e- brake and seat.
    There is one available that is essentially a knurled wheel that ratchets in or out.
    My memory tells me the screw is a countersunk Philips head, so you can't grab it with pliers.
    It's less than an inch or two tall and might get you past having to remove the seats.
    When you are finished the repair, don't install the Philips screw.
    Switch it to a hex head fastener so you won't need to worry about doing it again.

    Thanks all.

    I believe I have to get the seat out because it doesn’t appear like that cables are working properly.

    Also, when I disassembled the emergency brake handle and mechanism, I now can’t get it back together to operate properly.

    So I think surgery is required..... and it’s just such a pain in the a$$ to work on that hand-brake with the seat tilted up ....

    I replaced my handbrake cable with the seat in situ - can be done but is fiddly. The Jaguar workshop Manual says remove the seat first - which is what you intend. As Tony says - the work is straightforward. Motor the seat forward to expose and remove the 2 bolts holding the rear ends of the seat rails, then motor backwards to remove the 2 bolts in the front ends of the rails. Then lift the carpet under the front edge of the seat to expose and remove the the black metal cover panel over the ECU mounted on the floor (2 screws), remove the screws securing the plastic harness clamp, cut any cable ties and disconnect the multiplugs. As I recall, I also had to unbolt the seat belt anchorage bolt. You will probably need an assistant to get the seat out of the car (and back in again) without damaging adjacent trim etc.

    This may help you on re-assembly https://www.sngbarratt.com/uk/#!/Eng...%20AND%20CABLE

    I got the seat out, and the handbrake assembly is now connected and reinstalled. Still needs a little fettling on the adjustment of the cable, but I believe that I have solved the major challenges, and also vacuumed 23 years worth of grit, French Fries and hard candies out from under the seat and carpeting on the drivers side.

    Thanks for all the suggestions and support!

    Happy New Year to all!
