Heated Seats For Trophy.

I've just purchased both rider and pillion heated seats for my Trophy.
Fitted them as instructions but I have nothing coming up on centre LCD screen saying that they are on and working.
Do they need enabling with diagnostic tool?
Says that the fuse it the first one in front fuse box. This one is for the heated grips. Is this shared with seats too? This fuse is ok.
Can anyone help please?
Am I missing something?
Thanks.
Wayne.

 

Hi.
I've now found out that I need them enabled by a dealer.
Thanks.
