Adria Twin wiring identification help.

[haasad]

Hi all hoping for a little information please.
I was removing the abs ecu for replacement and identified a couple of cables and plugs obviously never connected but I’d like to know their function.
Firstly a black cable coiled in the underfloor battery box terminated in a miniature fin type plug with 6 pins.
Secondly two separate leads terminating in rectangular two pin plugs under the driver (RHD) seat.
Hopefully someone knows what they are for ?
Photos attached.
Thankyou
Andy

Could be for heated seats or any other options you don't have. Most vehicles have multiple connections hanging loose all over the place if you look for them.
I believe manufacturers use the same wiring loom for lots of vehicles to cut manufacturing costs.
