Thank you All for all the help and suggestions.
Even though we checked the fuses last night and none had actually blown,a fuse was the culprit,not sure exactly which one though imagine fuse 27.
So happy days and all now sorted.
Thank you once again

One last question or 3 😁 do the towing electrics need to be coded? And how will we know if they have/haven't already been done? Also is it essential to have them done if it is needed?

I guess the main thing is if the reverse sensors and disabled when a trailer is connected.
Otherwise don’t worry

Fantastic! Thanks Andy

And the suspension changes to. 2019 5.0 SC SVA (Current)

Thanks Brit Plumber,when we attached the electrics sensors seem to of been switched off so hopefully suspension will be fine also,will find out tomorrow.
