BMW E46 Passenger’s Power Seat Wiring (LHD)

This is the complete, uncut, passenger’s power seat wiring removed from a LHD E46 chassis harness that was being thinned for a racecar. This wiring can be added to another E46 to retrofit a stock power seat.

This wiring goes from the X275, 25-pin, Yellow connector of the Passenger’s Seat Connector to the Fuse Box and X494, Comb Splice, Chassis Ground Point – Passenger’s C-Pillar. A used 30A fuse is also included.

Wiring Details:

• 4.00mm² Red/Brown – X279-13 to Fuse 70 (30A)
• 4.00mm² Brown – X279-14 to X494

Notes:

– On a stock chassis harness this wiring is routed along the rocker panel and behind the dash.

– You do not have to attach this ground wire back to the X494, Comb Splice. You can cut the pin for the comb splice off and use a ring terminal to attach this ground wire to another suitable ground location.
