Bmw z3 pre tensioner plug problems (last owner adapt newest seats)

[mluism]

Hi Everyone I'm from Portugal and I have
Bmw z3 1996

Last owner bought newer seats and try do adapt... but not complete the job. I have airbag lights on.
Also he maybe bought an UK car seats (not sure if this is a problem, for example the driver side in my country is different so, plugs maybe different. not sure of this)

The seats have heated cables + electric adjustable - Work fine
They also have seat occupancy sensor - I will use a Bypass to resolve this
Missing the seat belt tensioner

I have this tensioner



and all this cables...

-Big plugs i know they are for heated and electric seats - Work fine
-White plug i think this is for seat occupancy sensor
-But blue plug i do not anything to connect!


I need to adapt to orange pre-tensioner plug? or missing any cable?

Below is a link to the Z3 wiring diagrams. You'll need to work through them to find the one for your car and the one for the car that donated the seats, then you can marry/connect up the wiring.

At the end of the wiring diagram you will find pictures of the connectors locations (component location views) and the drawings of the connectors (connector views). Just need to match them up but you will need the wiring diagram from the year of the donor seats and the diagram for the year of your car. The link above should get you started in the right direction.
