Side Airbag Precautions
If the vehicle is equipped with side airbags, the type of side airbag used will have an effect on
how the cables will be routed. The technician needs to use care when selecting the route that
they are going to run their cables. If the cable runs across an airbag, the cable could impede
the airbags deployment, or the cable could break and injure the passenger.
Kustom Signals, Inc. highly recommends that, where possible, cables should be routed away
from the airbags. For example, if the vehicle has side curtain airbags, it would be better to
route the cables under the doorsill trim plate.
Radio Frequency Interference (RFI) Prevention
Radio Frequency Interference (RFI) can cause operational problems, such as video or audio
distortion. Typically, RFI can be prevented by careful consideration of how the cables are
routed through the vehicle. The technician should follow these precautions:
DO NOT route the Eyewitness
®
HD system cables near the cables for the two-way radio
system.
DO NOT bundle the Eyewitness
®
HD cables with the cables that belong to other
systems.
In the event that RFI is causing distortion of the video or audio in the system, the technician
should check the routing of the cables for the Eyewitness
®
HD system. Make sure they are not
routed in the same area with the two-way radio system cables. Re-route the cables as
necessary.
Routing Cables Through Bulkheads
The installation technician needs to use care when routing cables through the bulkheads
(formerly referred to as firewalls) of the vehicle. When possible, the factory pass-thru (holes)
should be used. The pass-thru should be fitted with a grommet to prevent the sharp metal
edges of the bulkhead from cutting the sheath of the cable. If the technician is able move the
factory cables back and forth through the factory pass-thru, there should be adequate room to
route the Eyewitness
®
HD cables through the same pass-thru.
When determining which pass-thru to use, the technician should do a thorough inspection to
make sure that they will not be routing cables near the exhaust, heat shields, or rotating
components. They also need to use care to not damage the sheath on the cable.
It is advisable to use a tool to assist in pulling the cable through the pass-thru. The technician
may choose to use fish tape or an old aerial to help in routing the cable through the pass-thru.
The technician will feed the fish tape through the pass-thru from the side that they want to feed
the cable to. Once the fish tape is through the pass-thru, the technician will tape the end of the
cable securely to the fish tape and pull the cable through.
