Main Power Connections 

 

The system is designed to receive power and ground via the JBUS connector.  Only the 
Ignition wire is to be connected to a source of power.  The ignition connection should be 
made to a source of power other than the Accessory.   

 

Alternate Power Input 

 

In situations where the JBUS does not have power an alternate power input is supplied.  
Disconnect the 3 PIN connector, located behind the DB15 JBUS Input, and connect the 
External Power Harness (331-2022).  While it is not very common, there will be trucks pre 
2002 that only have Ignition power or simply no voltage at all.
