You have the later 1600 series hyd which is totally different than a pre-1992 1600. The easiest way to hook up the hydralics on a bubble up auger and the best in my opinion is to get longer hoses and run them along the frame to where you hook up your header and then just hook it in where your reel drive hoses hook up. We don't run our bubble ups in small grain or beans just in corn mainly because of grain damage and also because of added weight, I would be especially careful with a 66 if you use it in anything other than corn. The one thing we really like about hooking it up on the feederhouse is you can regulate the speed the auger turns in the cab. Good luck JHarvest
