5.3  CONNECT THE OBD-II WIRING HARNESS 
This section contains the information required to connect the OBD-II Wiring Harness. This harness 
enables you to obtain power and ground signal from the vehicle without splicing wires from your 
vehicle. Note that you must still connect the ignition sense wire to the true ignition wire on the vehicle.  
Note: If you are using the Standard Wiring Harness, skip this section and refer to 
Connect the Standard 
Wiring Harness. 
Before you can begin the OBD-II Wiring Harness installation, you must crimp together connections from 
your LMU-XXX wiring harness to the OBD-II pigtail. Join the Red Wire (power) and Black Wire (ground) 
from each harness using the supplied butt connectors. Note that some vehicles that feature OBD-II may 
require hard wiring due to signal strength. 
1.  Locate and remove the vehicle’s OBD-II port connector from the current vehicle mounting position.  
•  If the LMU-XXX OBD-II harness connector does not fit in the original factory mounting position, an 
optional flange is available.
