14. Run the antenna power-data cable (the end without connectors) from the top of the roof in to
the cabin through the grommet, and route the cable in the inside of the vehicle as desired to
reach the constant 12-volt power source.
15. Connect the power-data cable to the Wireless Matrix MBS2-LP by matching the connector
grooves and twisting the connector to its locked position.
16. Once the desired length of cable is exposed, use an outside clear silicone sealant to seal and
weatherproof the opening.
17. Select the point of access from the engine compartment into the cabin and drill (if necessary)
a 1/2-inch hole to run the power extension cable into the cabin.
18. From the engine compartment, identify the constant 12-volt power source (a direct lead from
the battery’s positive connector can be used).
19. Install the fuse lead of the power extension cable (red, 10 to 12 AWG, lead) and connect to
the positive battery lead or selected constant 12-volt power source (see figure 6).
