T6 heated seat wiring

I have upgraded the double passenger seat on my 2018 T6 to a single seat. The original seats were not heated so I have so relevant controls. The new seat is heated and I was hoping to wire it independently, powered from the auxiliary battery via a led on/off dash switch and a 30amp relay with a 10 minute timer.

The problem is I have a black plug under the seat with 3 wires (brown, brown/blue, black/white) as per photo, but can’t find out what each of the wires are. I assume 2 re for live and neutral.

Seen some very similar posts but none that exactly answer the question.

Anyone know what each of the 3 wires are?

black/white wire is temperature sensor wire and brown/blue resistance wire for the pads themselves which also splits further up the loom. Brown is a ground for all the pads and temp sensor within the seat pads
