Installing the power wire
Follow the appropriate set of
instructions on the following pages. Connect the power wire to a continuous 12 or 24 VDC
source (one that provides power even when the vehicle
is not running). This can be a direct connection to the
vehicle’s battery or a connection to a continuous
source on the vehicle’s fuse panel.
Connecting to a battery with top terminals
The following items are required for connecting the
power wire directly to a battery:
• A length of wire
• Two crimped splices
• A power drill and an assortment of drill bits
• A snap-in bushing
• A wire stripping/crimping tool
• A fuse link
• A 3/8 in. terminal ring
• A 3/8 in. by1 1/2 in. bolt
• Two 3/8 in. washers
• A 3/8 in. nut
• Socket wrenches or box wrenches
Refer to Figure 7 as you perform the following steps:
If the wire is not long enough, you
will need an additional length of
wire.
1. Determine if the power wire is long enough to
reach the battery’s positive (+) terminal.
2. If necessary, use a crimped wire splice (for #18
AWG) to join the additional length of wire to the
power wire after cutting off the spade lug.
3. If necessary, drill a hole through the vehicle’s
firewall for the power wire.
