Cables Routing and Connection Procedure
DC Power and Ignition Cable Installation
NOTE The VSM supports 12 V vehicle batteries, i.e. 13.8 V ±20% DC vehicle batteries.
The DC Power cable is equipped with 5-Ampere fuse (slow-blow). Verify that the vehicle electrical system can support
current values larger than that.
Connect the fuse in the red wire to the power source using the shortest practical length.
The unit is only for use with a negative ground system.
See Figure 2-10 before routing or connecting the DC Power and Ignition cable and use the following process.
Figure 2-10
DC Power and Ignition Cable Routing Into Engine Compartment
Process 2-4 describes how to install the DC power and ignition cable.
CAUTION Insert the fuse after making and carefully inspect all connections.
Process 2-4
How to Install the DC Power and Ignition Cable
1
Route the DC Power cable’s leads through the bulkhead and into the engine compartment. Use an existing
opening or, if necessary, drill a 2 cm (26/32 inch) diameter hole through the bulkhead. Insert a grommet into
the hole to prevent damage to the DC Power cable.
2
Cut the black lead to the desired length and connect it to the negative (-) battery terminal.
3
On the engine side of the bulkhead, connect the red (A+) lead to the vehicle’s battery as follows:
a. Cut the long red lead to the desired length. Verify that the fuse holder is at a distance of 20-30 cm away
from the connection point, ensuring that it is not close to any hot engine component.
b. Mount the fuse holder using the provided mount, and dress wires as necessary. Connect the red lead
plug adaptor (on the fuse holder) to the matching receptacle on the red lead of the DC Power cable.
c. Remove the fuse from the fuse holder and connect the red lead of the DC Power cable to the positive (+)
battery terminal. Cable tie the wire every 4” (10 cm) along its length, do not tie to existing vehicle
systems.
d. Insert the fuse into the fuse holder.
