aligned to each other. The two 18 pin connectors MUST also be aligned. This means that the

4. With the colored side of the control head extender cable facing upward all the way between
the control head and the chassis connect the cable to both control head and chassis 18 pin
connectors. After the cable is connected the control head can be uprighted.
If the cable is plugged in upside down the control head will
burn out.
