2.
Splice the white/yellow wire in the horn ring cable to the horn ring side of the wire
that was cut in step 1. Insulate the splice with a wire nut (supplied).
3.
Splice the white wire in the horn ring cable to the horn side of the cut wire.
Insulate the splice with a wire nut (supplied).
To connect the lamp:
1.
Connect the red wire to the dash lights circuit or to a vehicle circuit that is
powered when the ignition switch is “on.” This connection will supply power to the
Control Head panel lights whenever the headlights are “on” or the vehicle ignition
key switch is in the “on” position.
2.
Connect the black wire to the negative battery terminal.
The Control Head can now be secured to the vehicle dashboard.
Amplifier Power Connections
When making the power connections to the PA4000, each wire must be terminated
with an appropriate 1/4-inch female, insulated, quick-connect terminal. Complete the
wiring to the unit as follows:
1.
Crimp the 1/4-inch female terminals on one end of user-supplied, 14-gauge red
and black wires. See Figure 1 on page 13. Connect the red wire to the “POS”
Amplifier connection. Connect the black wire to the “NEG” Amplifier connection.
DRILLING PRECAUTIONS: Before drilling holes, check the area into which
you plan to drill to ensure that you do not damage vehicle components. All
drilled holes should be deburred and all sharp edges should be smoothed.
Additionally, all exterior drilled holes must be sealed with Motorcraft seam
sealer T-A-2-B or equivalent to prevent the potential exposure to carbon
monoxide or other potentially harmful fumes. Failure to observe this warning
could cause serious injury or death.
2.
If the amplifier is installed in the vehicle passenger compartment, drill a 5/8-inch
hole in the vehicle firewall for the power and ground leads.
3.
If necessary, drill a 5/8-inch hole in the vehicle firewall. Install a user-supplied
5/8-inch grommet, or similar device or material, to protect the wiring and cabling
against damage from rough edges.
4.
Route the leads from the amplifier to an area near the battery. (Do not connect to
the battery at this time. If necessary, pass the lead through the 5/8-inch hole that
was drilled in step 2.
5.
Connect the black wire to the negative battery terminal. A secure mechanical and
electrical connection is required.
