Hi Mate, by any chance would you mind sharing the dump file for your new cluster? I had a bad read and now my new colour cluster is blank. Yours looks identical to what I have. Would be a huge help if you're able.
I actually understand the airbag circuit modification, I'd be happy to post schematics for others assuming I can get this one working.
My post is here with more information about the vehicle
