1)   Remove the P2 terminal block (

 in Figure 22) 

from the DVR back assembly. 

2)  Connect the audio and power cables from the  

microphone as shown in Figure 29. 

Note: For instructions on making wiring connections at the microphone  
end, refer to the instructions provided by the manufacturer. 

 

 

 

 

 

Power is supplied through the DVR’s four-pin Molex connector, located on the DVR Rear Panel Assembly  
(

 in Figure 22). The following connections from the vehicle junction box must be made to the DVR:  

+12-VDC continuous with 6-amp circuit breaker source, circuit battery ground, chassis ground, and  
+12-VDC ignition/engine running with source fused not greater than 1 amp. See Figure 30. 

1)  Run a four-conductor 18-AWG wire from the  

vehicle power source to the DVR location. 

2)  Make connections to the vehicle source (contact the  

vehicle manufacturer for information on connecting  
to the vehicle power source). 

3)  Crimp the wire pins using a Molex crimper, and  

make connections to the DVR’s four-pin Molex  
according to Figure 30. 

4)  Test the four-pin Molex wire-harness for power  

(both continuous 12 VDC and engine  
running/ignition). 

Note: For a working definition of engine running/ignition,  
contact the vehicle manufacturer. 

5)  Plug the Molex connector into the power connection on 

the DVR Rear Panel Assembly  
(

 in Figure 22). 

Check the power connections with a voltage meter  
to ensure correct polarity and connections.
