4) The 8051 development boards need to be plugged into the control and meter box modules to ensure the
proper delivery and receiving of CAN information. Each 10-pin connector from the modules should be
plugged in such that Pin #1 aligns with the corresponding Pin #1 on the port of the MCU. If this has been
plugged in correctly, the ribbon should be facing towards the power connection of the board. The red
stripe indicates pin 1 on the left side. This correct configuration is shown in the following Figure 12.

5) The Control module has 3 wires and one 10-pin connector. The black wire should be attached to analog
ground (J20-8) and the red and green wires are to be attached to the ADC outputs (J20-6 & J20-5
respectively). These values read in from the two potentiometers are specifically used for steering and
