Nissan Micra 1.2 SE - Ocober 2004 - Unexpected Strange Switch? - Nappa

I want to remove the rear sliding seats on my Micra to give me more load space.

Fitted in the R/H plastic trim that covers the rear mounting position of the sliding seat frame there is an electrical plastic item (Switch?) that is about 70mm x 19mm x 8mm.

The only ID is the numbers 04 01 16 printed on it. 2 wires.

I Can find no reference to it & wondered if it may be aside impact sensor? But wouldn't there be another in the L/H trim cover?

Can anybuddy ID this or know what it is?

Thanks

For interest, I believe it is the rear antenna for the door lock system. The manual states that this is under the rear seat.

There's nothing there except access to the fuel tank unit also the line drawing shows an item similar to to the item I have queried about..
