STEP 2 – ATTACH POWER
In order to avoid potential discharge of static damaging the unit, confirm that the unit is off prior to beginning
installation sequence.
NOTE
: To prevent issues with power supply we suggest that these connections be soldered and not
installed using connectors. Fluctuating power supply will cause the unit to behave erratically.
PIN 1
PIN 1 should be connected to constant vehicle power as close to the battery as possible. It should also be
fused with a 3-amp inline fuse. The HawkEye 5500 can be attached behind a master battery cutoff switch
if necessary, as the internal unit will run on backup battery if required. This pin is used for running the unit
and charging the battery.
PIN 2
PIN2 should be connected to a good and safe ground point, ideally as close to the negative terminal of the
battery as possible.
PIN 3
PIN3 should be attached to ignition switched power. No current is pulled through this line as it is used for
powering off and on the unit with the vehicle. This PIN must be powered in order for the unit to remain on.
As soon as power is lost, the unit will begin its shutdown timer.
There are typically two types of switched power in a vehicle, each with their own benefits and drawbacks.
Ignition Power:
Power that is only turned on when the engine is running. Use this type if you want the unit
to only report when the engine is on. This is the preferred method of powering the unit.
Accessory Power:
Power that comes on when the key is turned to the accessory position, but the engine
is not necessarily started. This is what systems like the radio run off and may be easier to locate. Use this
type if you want to report or utilize the Bluetooth functionalities before the vehicle is started.
WARNING:
Using this mode will prevent the ‘idle’ event from properly functioning.
A vehicle electronics installation technician can help locate the best source of switched power available.
Typically, there are two locations power can come from.
1) The ignition switch itself
2) The interior fuse panel which is usually located in the driver side footwell
