2.6. Step 5: 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 2-7.
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 lines from the battery have a voltage drop across them
because of current drawn by lights, blowers, and A/C units, for example.
2. If there is a master battery switch in the battery compartment connected to the
battery’s negative (–) terminal, then 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:
The supplied in-line automotive fuse holders are for protecting the red
battery positive wire and the yellow ignition trigger wire. Butt-splice connectors are
supplied to connect the fuse holders to their respective wires. The battery positive fuse
holder uses the 5 A automotive blade fuse, and the ignition trigger fuse holder uses the 1 A
automotive blade fuse.

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 detects the low voltage and stop recording to protect itself. If the
voltage stays low for too long, the DVR interprets this as meaning the vehicle battery is
drained and the DVR shuts down completely.
