Fuse Taps/Add-A-Circuits Suggestions
If you're connecting fuse taps/Add-A-Circuits to the fuse panel, use the following criteria to
select appropriate locations for the Constant Power and Ignition connections.
1. Connect to open circuits without a fuse already in place, if available.
2. Connect to slots for non-critical functions (e.g. radio or power windows). Avoid
connecting to critical functions (e.g. airbags or control modules) as this may cause the
vehicle to be inoperable and/or create a safety hazard. Refer to the examples below.
Best slots:
l
radio
l
power outlet
l
heated seats
l
power seats
l
power windows
l
upfitter/auxiliary options
Good slots:
l
power mirrors
l
HVAC controls
Slots to avoid:
l
control modules (ECM, BCM, TCM, etc.)
l
lights (headlights, taillights, brake,
hazards)
l
airbags
l
horn
l
fuel pump
Basic Event Recorder Electrical Connections
A minimum of three connections are
required for the event recorder to function.
These leads are found on the Vehicle Inter-
face Cable terminating at the female end of
the Molex connector.
1. Red wire: Provides primary power
and must be connected to a
continuous power source. This lead
has a 5-amp inline fuse.
2. Brown wire: Functions as an ignition-sense, used by the event recorder to perform
functions such as activating the Infrared Illuminator when the vehicle ignition is
switched on or activating Hibernation mode when the ignition is switched off. This lead
has a 1-amp inline fuse.
3. Black wire: Functions as ground. This lead has a 5-amp inline fuse.
