About 737NG OFFSETS

Hi,I'm a cockpit builder and I'm using actually the 737NG over FS9.Actually, my project is stopped due to an important reason:I need to program SIOC code of AUTOBRAKE switch, but I have a problem with 737 PMDG offsets. Standard FS offset $2F80 does not works.I tried the AUTOBRAKE offset $62AA found at various websites, but it didn't work. I know that PMDG offsets aren't published.I would to like two things:1.- It's possible to obtain a list of 737NG PMDG offsets? (At least autobrake offset)2.- The new 737NGX will come with public offsets, or will remain private?I like PMDG's 737NG. I think is the better plane for Flight Simulator, and I have many expectavives on the new NGX plane. But most builders we are forced to leave this plane because you do not publish the offsets.I'd hate to have to buy another plane from another brand, but the cockpit builders are required to do so if we do not have offsets, becouse we can not continue our project. It's a shame.I would like to know your plans about this question.Thanks,Agus
