2.5. Step 4: Connecting the Power and Ignition Harness,
Fuses, and Fuse Holders
The power and ignition harness uses a pair of 16 AWG power wires to connect to
the vehicle battery and a 22 AWG yellow wire to connect to an ignition-switched
circuit. See Figure 2-5.
The supplied in-line automotive fuse holders are for protecting the red positive (+)
battery wire and the yellow ignition wire. The 5 A fuse and in-line fuse holder are
supplied for the red positive (+) battery power wire. The 1 A fuse and in-line fuse
holder are supplied for the yellow ignition trigger wire.
To connect the power and ignition harness to the battery:
1. Connect the battery power wires as close to the battery as possible.
The battery acts as a very good filter for transients and surges on the vehicle
power lines. Also, the cables from the battery have a voltage drop across them
because of the current drawn by the lights, blowers, and A/C units, for
example.
2. Connect the black negative (–) battery power wire to the battery’s negative
(–) terminal. If there is a master battery switch in the battery compartment
connected to the battery’s negative (–) terminal, connect the black negative
(–) battery power wire after the battery switch.
3. The in-line fuse holder consists of a black plastic piece with an attached cap
that simply pulls apart. Install the appropriate fuse and push the holder back
together.
4. Strip the red wire end appropriately. A butt splice connector is supplied to
connect the fuse holder to the red battery power wire. Connect the other end
of the fuse holder directly to the battery’s positive (+) terminal.

Important:
Connecting the power farther from the battery will result in a larger
voltage drop (reduced voltage from the battery to the DVR). If the voltage drop is too
large, then the DVR will detect the low voltage and stop recording to protect itself. If the
voltage stays low for too long, the DVR will interpret this as meaning the vehicle battery
is drained and the DVR will shut down completely.
