Welcome to the forum.
I haven't got a diagram I'm afraid,but one thing that might be worth considering is finding a plug with wires attatched from another late model Renault at a breakers yard and matching up the wires by colour.I certaintly wouldn't let Renault fit a new loom as (you quite rightly say) this would cost a crazy amount of money.
I'd rather push my Alfa than drive a BMW....
