Power cable connections to the vehicle

1Attach the ring terminal of the black lead to chassis ground using the appropriate hardware.

2Ensure that a good mechanical and electrical connection has been made to the chassis, then coat the connection with anti-corrosive spray.

3Connect the red lead to the battery positive (+) terminal.

4Connect the ignition sense lead as described below.

5When installation is complete, secure any loose wires.

6Route the cable through the vehicle to where the E6473B is installed.

Ignition sense lead

NOTE

Connect the ignition sense lead of the power cable to a source that measures +12 volts only when the ignition switch is on, using one of the following methods:

Connect it to the radio side of the radio fuse.

Connect it to a 12 volt power lead that is switched on and off by the ignition switch.

Direct Connect Hub: If you do not connect the ignition sense lead of the power cable for the hub, the unit can only be powered on and off via its front panel switch.

The ignition sense wire color code is specified under “Main power cable" on page 177.

Connecting the ignition sense lead to the fuse block

Because each vehicle is different, you must determine the best method for attaching the lead to the fuse block. Agilent recommends that you crimp a quick-disconnect terminal onto the lead, then plug the terminal into the fuse block.
