a Packard Electric “Weather-Pack” con-
nector (DC power Connector).
The DC Power connector has:
•
At position “A”, the smaller red
switch-sense wire (commonly to igni-
tion)
•
At position “B”, the blue ground wire
•
At position “C”, a larger red B+ DC
power wire (MUST be unswitched)

3.
Place this connector at Gemini
PD
’s radio
power input location. Do not connect at
this time. See paragraph 2.6 “Complet-
ing 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 lo-
cations along their length.
Caution:
Use proper crimping tool.
Common pliers are NOT
acceptable.
Warning:
The DC Power lead must be
unswitched
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 negative wire at the battery
ground and the positive lead at the bat-
tery positive. 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 Gemini
PD
turning ON and OFF
dependent on the vehicle’s ignition
key.
•
Connect to “Accessory” if you wish
Gemini
PD
to be available when the
engine is not running, but still de-
pendent on the ignition key.
•
Connect to a user-supplied control
switch.
•
In installations equipped with a
“ChargeGuard”, connect to the
controlled-side of the ChargeGuard
(remembering that the DC Power
lead must NOT be switched).
10.
Make appropriate connections.
Cautions:
Where scraping to bare metal was
required, and at the battery posts
where wire ends and lugs may be
exposed, apply anti-corrosion com-
pound.
Insert the fuse only when installa-
tion is complete and ready to test
.
11.
At the Gemini
PD
position, neatly coil
cable slack and attach securely.
