shown in Figure 5. Please ensure that the chassis point has been cleaned and scraped of any
dirt, paint or other material that may prevent a good electrical connection.
If one ring lug cannot hold all the wires, add an additional ring lug and connect it to the
battery's negative terminal (-) or to the same chassis point by using the same installation
screw. Connect this common lug to the common, grounded chassis point or to the battery's
negative terminal (-) as shown in Figure 5. Make sure that all the ring lugs are placed on
clean and unpainted surfaces.
Power Cable Installation
1. Determine a routing plan for the power cable, taking into consideration the location at
which the unit is to be mounted, and the location of the vehicle battery.
2. In order to pass the power cable through the fire wall and into the engine compartment,
locate an existing hole with a grommet in the vehicle fire wall, or drill a 10 mm (0.4 inch)
access hole at the desired location. Insert a grommet with a 5 mm (0.2 inch) inner
diameter into the access hole to avoid damage to the cable (see Figure 6).
Take special care not to damage any existing vehicle wires.
3. From inside the vehicle, route the red and black power cable leads (without lugs attached)
through the access hole into the vehicle’s engine compartment, using accepted industry
methods and standards.
4. Locate the nearest available vehicle chassis ground mounting point and shorten the black
lead to remove excess cable length.
