This is from JD Service Advisor, this should tell you about the single point hookup.

When the combine is attached to any header without a reel (for example a corn head or a belt pick-up head), no reel raise/lower cartridge will be present in the header multi-coupler half. Pressing the reel raise switch (feeder house speed increase) will send pressurized oil from the valve stack through an internal passage in the combine multi-coupler housing to the feeder house speed cylinder.

When the combine is attached to a platform header, a reel raise/lower cartridge will be present in the header multi-coupler half. When the multi-coupler is connected to the header, the reel raise/lower switch in the cab will raise and lower the reel normally. To increase feeder house speed, the multi-coupler must be disengaged and the operator must press the reel raise switch on the multifunction control handle.

Due to the internal design of the multi-coupler cartridges, when a combine with the variable speed feeder house option is connected to a platform header, feeder house speed will automatically slow to minimum when the reel is fully lowered. Feeder house speed then cannot be increased until the multi-coupler lever is disengaged.

IMPORTANT:
When using a cutting platform, feeder house backshaft speed (header speed) must be as slow as possible to prevent accelerated wear of the cutterbar and to avoid excessive header vibration.

I learned this the other day when hooking up a 9660 walker to an 893 head. Apparently the reel hyd oil also has an internal bypass when using a corn head so the oil can flow thru.
