3.  Place this connector at G3’s radio power input location. Do not connect at this time. See paragraph

2.6, “Completing the physical installation”.

4.  Carefully route both the B and the C wires to where the in-line fuse holder will be installed, usually

as close to the vehicle’s battery as practicable. Ensure that leads do not chafe on any metal part(s).
Secure the wires at several locations along their length.

5.  Insert the negative (blue) lead into one of the appropriate connector lug and crimp solidly to force the

metal contacts onto the wires.

6.  Repeat the step above for connecting the red DC power lead.

7.  Attach the positive lead at the battery positive terminal. Attach the negative wire at the vehicle end of

the battery ground cable.

If the negative cable is connected directly to the battery negative terminal, it should be fused in
case of failure of the vehicle’s ground cable.

Ensure tight and secure connections.

8.  Fasten the fuse holder and leads.

9.  Carefully route the “A” wire to where the connection will be made for switch sensing.

•

  Connect to “Ignition” if you wish to have G3 turning ON and OFF dependent on the vehicle’s ig-

nition key.

•

  Connect to “Accessory” if you wish G3 to be available when the engine is not running, but still

dependent on the ignition key.

•

  Connect to a user-supplied control switch.

•

  In installations equipped with a “ChargeGuard”, connect to the controlled-side of the Char-

geGuard (remembering that the DC Power lead must NOT be switched).

10.  Make appropriate connections.

Where scraping to bare metal was required, and at the battery posts where wire ends and lugs
may be exposed, apply anti-corrosion compound.
Insert the fuse only when installation is complete and ready to test.

11.  At the G3 position, neatly coil cable slack and attach securely.

The main transmitter antenna must be vehicle-mounted to provide a separation distance of 50 cm or more
from all persons and the antenna gain must not exceed 5dBi (with a 1.6dB cable loss).
