Talk about the 406's electrical system, what wires do what, how to add extra functionality, etc.

Underseat ECU

Post by gray »

hello friends
just wanted to know if the under seat ECU to control the seats and power mirrors from a coupe would work with a saloon?

i have a 2000 406 saloon 2.0 petrol RFV motor, when i bought the car it was missing the ecu under the seat but it looks like the wiring loom is there including the computer like pin connection.
would this also need to be programed with pp2000?
any help would be appreciated

It *should* but no guarantees. I haven't heard of anyone keeping the ECU when retrofitting seats. These are normally thrown away.

The seat ECU from a Coupe would be different as it needs to deal with the auto glide function for the rear seat access, i think i read the other day the wiring wiring/pinout is slightly different too
