Hi all ,in the process of retro fitting 2 electric front seats to my D2 , got heated switches ok and plugged in , also have looms from control switches from central console to seats.....question where does the power come from.....can't see anything. Photos would be very grateful.

Best regards John

It's a bit difficult to actually tell you where the power is picked up for the electric seats, but all the wiring information you need is in RAVE, which is almost essential if you're going to do any electrical work on the D2.
Also, you're going to need a compatible code reader such as Nanocom, Hawkeye or Lynx to activate the circuitry in the BCU. This from the Nanocom user's manual.

RAVE can be downloaded free from:-

Whether you're going to try to do the installation of the seats to match the OEM standard method or you're going to pick up the power without going through the BCU, I would still recommend you take a good look at the wiring diagrams.

Thanks for that Brian, I have Rave and Nanocom , I have come to the conclusion that the plug to power seat motors has either...not been there to start, under the carpet or been removed I will investigate further . other option is to convert seats to manual...is that difficult do you know ?

cheers John

I would venture that you're missing some parts, namely the "satellite fuse boards" and the seat relays R209 and R210.

Seat movement.
Referring to the diagrams from RAVE, power for the electric seats is via link 5 (50 amp) which splits to the right and left seats. The right and left seat circuits are identical, so we'll stick to the right hand seat, the left hand seat refs are shown in the square brackets.
The brown wire from the engine fuseboard feeds to the relay R210 [R209]. This relay is triggered from the BCU. The switched power from the relay is then fed via fuse 2 (40 amp) on the satellite fuse board P133 [P132] and from there into the switchpack on the seat. Power for the lumbar support pump is then fed back out to the satellite fuse board via F3 and F4 to the pump.

Seat heating.
The seat heaters are fed from a different supply, via the link 7 (30 amp) in the engine compartment fuseboard, switched by the "auxiliary circuits" relay R101 on the engine compartment fuseboard and via fuse F15 (20 amp) on the passenger's compartment fuseboard. From there it splits in header 0761 and then to the individual seat heater switch S161 [S162]. It then feeds to the seat heater module D178 [D177]. This module controls the power fed to the seat heaters and is itself controlled by the thermostatic sensor in the cushion heater,H119 [H118]. The cushion and squab heaters are wired in series so that the one sensor can control both heaters on the seat. Seat heating is available on some manual seats as well as electric front seats. The switches for the seat heaters are built into the window control panel on the central console.







The "satellite" fuse boards, if they are present should be located under each seat:-



Converting powered seats to manual, I have no idea but I would think that it's not that easy.
