The CV expansion board should have a 10 pin ribbon cable attached to it. The ribbon
cable should be carefully plugged into the Engine mainboard. Please pay attention to the
connector orientation, there is an orientation key on both the ribbon connector and the
header. If you have trouble connecting the ribbon cable, it can help to unplug it from the
CV expansion board and plug it into the mainboard first.
After plugging in the ribbon cable, carefully slide the CV expansion board into the Engine
chassis. The mounting holes of the expansion panel should meet up with the threaded
holes. Replace and tighten the hex screws to hold the expansion board in place.
