Strain Relief Grommet

Accessory Pigtail Cable

R170

Proceed as follows to install the power cable:

1. Before beginning power cable installation, remove 

the negative cable from the battery to prevent 
damage from accidental short circuits.

2. Route the red and blue wires of the power cable to 

the vehicle battery. You may need to cut the cable if 
it must be routed through an opening that is not 
large enough to clear the fuseholder. The -422 kit 
includes butt splice connectors that can be used to 
splice the cable back together. 

3. Connect the red power cable to the positive (+) 

battery terminal. To minimize the chance of a short 
circuit occurring in an unfused part of the power 
cable, the fuseholder should be as close as possible 
to the battery terminal.

4. Connect the blue power cable wire to the negative

(–) battery terminal.

5. Both 7- and 15-ampere fuses are included with the 

power cable. Install the 15-ampere fuse in this 
application.

6. Plug the power cable into the transceiver and recon-

nect the negative battery cable.

7. Install the antenna according to the manufacturer’s 

instructions. This transceiver has a miniature UHF 
connector. If the antenna has some other type, an 
adapter is required. Check VSWR. Reflected power 
should be less than 4% of forward power (VSWR 
less than 1.5 to 1).

2.4.1 GENERAL

If transceiver power is to be controlled by the 

vehicle’s ignition switch, a horn alert installed, 
or other accessory connector outputs utilized, the 
optional accessory pigtail cable is installed in the 
transceiver (see Figure 2-1). Also required is the 
accessory wire kit which includes two 8-pin connec-
tors which plug into the pigtail cable, two 22-ft and 
three 2-ft wire assemblies, and a fuseholder assembly. 
These components are installed as required for each 
application. Proceed as follows to install this cable.
