E Permanent In-Vehicle Hardware Installation
Speed Pulse Cable
This cable is only included if you have ordered the Agilent
direct connect GPS DR with mag mount antenna (E6473B
option 030) or with permanent mount antenna (E6473B option
031). The GPS DR requires the Speed Pulse cable
(E6473-60207), which is connected to the vehicle’s digital
odometer or speed pulse lead.
General Installation
1 Locate the emergency brake cable grommet, at the point
where the cable passes through the firewall.
2 Cut a slot in the grommet to allow the Speed Pulse cable to
pass through it.
3 Feed the cable through the grommet into the engine
compartment.
4 Connect the black lead with the ring terminal to the vehicle
chassis.
5 Connect the black terminal to the speed pulse ground lead
using a wire tap.
6 Connect the red terminal to the speed pulse lead using a wire
tap.
7 Connect the white terminal to the positive lead of the backup
light using a wire tap.
8 Route the cable through the vehicle to where the navigator is
installed.
NOTE
The odometer pulse lead typically originates from the computer module
(PCM) in the engine compartment. Contact Agilent Customer Support for
assistance in locating the correct lead in your vehicle.
For vehicles not equipped with a digital speed pulse signal, an analog
speedometer pickup utilizing a Hunter Universal Transducer is available.
Contact Customer Support for details.
