OEM Sport Electric Leather Seats Retrofit

 

Finally after several efforts I managed to source a complete leather sport interior for my E46. Everything were plug and play apart from the connections for the electric motors under the seats. Following a very comprehensive guide online I managed to connect everything together. Power is drawn by 2x30A fuses from the fusebox directly using the always on 12v supply.


Fuse positions #65 and #70 are vacant and are dedicated to the Power Seat Adjustments so you only have to run:
12 Gauge + and - to the Passengers side seat and....
12 Gauge + and - to Drivers side seat plus an additional wire for the K-bus location in the fuse panel. This is to activate the memory controls for the drivers side seat.

 

Drivers Side (25 Pin Plug)

Pin 13 - Power (Connect the 12 Gage Wire you ran to the seats at this Pin)
Pin 14 - Ground (Connect Ground here)
Pin 15 - K-Bus (Connect the wire that went to the comb connector full of Red/White/Yellow wires to this pin, it is for the memory fucntion ONLY and will not affect the Power seat Motors)

Passengers Side (25 Pin Plug)

Pin 13 - Power (Connect the 12 Gage Wire you ran to the seats at this Pin)
Pin 14 - Ground (Connect Ground here)

 

The rest of the panels (rear seats, door panels, rear section panels, armrests, headrests are plug and play).

 

Here's the end result:
