Seat Occupancy Mat Emulator Installation

BMW E-Series – male pins, 6-pin connector

Click the image below to enlarge the general installation instructions

In some BMW E-Series models, a 6-pin seat occupancy mat connector is used. It is located in the yellow connector under the passenger seat, as shown in the photo below.

For this type of installation, we offer emulators equipped with male pins, designed to be connected directly to the factory connector.

Important: Work on the SRS system should be carried out in accordance with the vehicle manufacturer’s service procedures. Installation should be performed by a mechanic or a person with appropriate knowledge and experience in SRS systems.

Removing the pins from the factory connector

Before starting the installation, switch off the ignition.

The factory seat occupancy mat connector has three wires: white, red, and brown. To remove the mat wires from the connector, gently press the locking tab on each pin and carefully slide the pin out of the connector housing.

The photo below shows the exact area where the locking tab should be pressed in order to release and remove the pin.

Do not use excessive force. Once the locking tab has been pressed correctly, the pin should slide out easily.

Connecting the seat occupancy mat emulator

After removing the factory pins, connect the emulator pins in their place, keeping the wires in the same color order.

During installation, take particular care not to short-circuit the wires or allow the exposed pins to come into contact with each other.

After connecting the emulator, make sure that all pins are seated correctly and cannot slide out of the connector.

Connecting the seat belt buckle emulator

Once the seat occupancy mat emulator has been connected correctly, the seat belt buckle emulator should also be installed.

Clearing the fault code

After the installation is complete, the ignition can be switched on.
In some cases, the warning light may go out automatically. However, the previously stored fault code usually remains in the control unit memory and must be cleared using appropriate diagnostic software.
