My 4.8is came with pretty much all the options ticked apart from rear electric reclining seats and the heated steering wheel. So I decided to retrofit the reclining seats option.
The main items you need are the motors and switches, but then ideally it's good to have the boot side panels too. You can however cut the original panels and purchase the plastic covers to bond in place.
As I'm a bit of a perfectionist, I waited for the panels to come up on the Bay (as I'd already purchased the motors and switches), but then sods law the complete retrofit kit came up (motors, switches, side panels and rear panels too).
It's plug and play and the kids love it when they are feeling a little tired.
I'm selling the spare motors and switches and also giving my original boot panels for you to cut up (unless like me you want to purchase the original panels).





You can see on the original panel where the motor fits:

Location for the rear switches:

Location of C pillar switches:

Can see the covers that allow the motors to move through:

I'm happy to help with the retrofit, etc.
