into J22 on the A19 Daughterboard.
J22 is a 30-pin connector and the ribbon cable extender has only 20 pins. Align the ribbon cable extender
with the pins on the left side of J22. When the ribbon cable extender is properly installed, you will see
two rows (5 pins each) on the right-side of the ribbon cable extender.

1. The ribbon cable extender needs to be assembled by the user. It consists of two connector plugs
(part number 1252-1010) and approximately eight inches of ribbon cable (part number 8120-2226).
The ribbon cable contains 26 wires; six of these wires need to be stripped off before being connected
to the plugs.
