Best/Easiest Heated Seat Kit

Hi all,

Does anyone know which would be the best/easiest kit for installing OEM heated seats?
I want the factory switches, rather than aftermarket.
FCX kit is £150 and “TOTALLY plug and play”.

The Mobile Centre kit is £96 and comes with a relay to make install “Easy”.

I had assumed I would get an Auto Electrician to do the work, but I would still like to get the best/easiest kit.

Thanks very much

Owen
