INSTALLATION
Installation Procedure
Begin the DC power cable installation as follows:
1.
Determine a routing plan, keeping in mind where the terminal is to be mounted and make
sure that the cable does not rest on sharp edges.
2.
Locate an existing hole with grommet in the vehicle fire wall, or use a 9.5 mm (3/8-inch) bit to
drill an access hole in the fire wall. Install a grommet with a 5 mm (3/16-inch) inside diameter
into the hole to protect the power cable.
3.
From inside the vehicle, feed the red and black leads (without the lugs attached) through the
access hole and into the engine compartment. (see Figure 1)
4.
Connect the black lead of the DC power cable to the nearest vehicle chassis ground point
(using the provided ring lug if necessary). Shorten the black lead to remove any excess cable.
(see Figure 2 Power Cable Assembly).
Improper handling with the power cable may cause short-
ing to ground. Ensure that during terminal installation the
power cable fuse is removed.
Be very careful not to damage existing wires.

Power Cable Routing into the Engine Compartment
Locate a good vehicle ground point. The vehicle frame
provides the best ground. Optimum terminal performance
can only be achieved with a very low resistance ground
connection. Verify that the connections between the bat-
tery negative terminal, vehicle chassis, and engine block
have low resistance.
