Connecting the Power Cable to the Vehicle Battery
The power/external inputs cable looks like the following:
Figure 15
1.
Route the power cable to the vehicle battery.
Note:
For the Chevrolet Tahoe with a dual battery configuration, use the passenger side battery if
possible. The passenger battery is considered an auxiliary battery for electronics.
2.
When routing the power cable, use factory firewall holes and grommets if possible.
There are usually several factory firewall ports giving access to the engine bay. Use the one that is the
easiest to access.
Ford Crown Victoria
– factory grommet is on the front foot-well on the passenger side.
Dodge Charger
– battery is located in the trunk. The power cable can be routed down the passenger
side rail and under the rear seat in the factory wiring channel that runs back to the battery.
Chevrolet Impala
– use the driver door grommet and go through to the inside of the fender to the front
of the engine bay.
Chevrolet Tahoe
– the following example is from a Chevrolet Tahoe – a small grommet hole is behind
the factory fuse block located on the driver’s side foot-well. Remove the rubber gasket, slit a small hole
in the grommet and pass the power cable through to the engine bay.
