Does anyone know where all the parts of the TVSS system are? I've found the ultrasonic adjustment next to the gear stick, the transponder key ECU behind the glove box and the siren under the bonnet. I'm guessing there is probably a main ECU somewhere - I'm looking for the part that receives the key fob transmission - I know it's not the transponder key ECU as the fob works with it disconnected.

Any help would be appreciated.

Cheers
