Breakout box connection, continued
Connect adapter 9813194 to the module connectors (toward the wiring) and connect breakout box 9813190 to the adapter.
Control module connections #A1-#A30 correspond to #1-#30 on the breakout box and #B1-#B16 correspond to #31-#46 on the breakout box.
CD player connections #1-#16 correspond to #31-#46 on the breakout box.
TMC/FM receiver connections #1-#10 correspond to #47-#56 on the breakout box.
The breakout box is designed to make it easier to read control module output and input signals when the module is connected and the resistance of the cables and components when the module is disconnected. Using the breakout box reduces the risk of unintentionally short-circuiting cables or damaging connector pins.
As the TMC/FM receiver does not have its own ground connection, there is no need to check TMC/FM receiver ground terminals.
