Hint: Control module terminals #B1-B22 are the equivalent of #31-#53 on the breakout box. The control module terminals in connector A are not connected to the breakout box.

- The breakout box is designed to facilitate reading off control module in and output signals when the control module is connected and the cable and component resistance when the control module is disconnected. Using a breakout box reduces the risk of accidental short-circuits and damaged connector pins.
