Rear Sceen Demister

As the one for my build is broken, and its going to be one of the last things i buy!!
I was wondering if anyone fancys measuring the resistance across their demister wire on there rear sceen?
Pref Without it connected as i want to try and exclude the resistance of the wire feeding it!
Only reason i need this is so i can work out what wire i need to run for it when i build my loom!!
Cheers,
Steve
