Connecting the System
Before installing the unit
• This unit is for vehicles with a 12-volt battery and negative grounding. Check the battery
voltage of your vehicle before installation.
• To avoid shorts in the electrical sys-
tem, be sure to disconnect the (–) bat-
tery cable before beginning installa-
tion.
To prevent damage
• When disconnecting a connector, pull the connector itself. Do not pull the lead, as you
may pull it out of the connector.
• If this unit is installed in a vehicle that does not have an ACC (accessory) position on the
ignition switch, the red lead of the unit should be connected to a terminal coupled with
ignition switch ON/OFF operations. If this is not done, the vehicle battery may be
drained when you are away from the vehicle for several hours.
ACC position
• To avoid short-circuiting, cover the disconnected lead with insulating tape.
• Attach the connectors of the same color to the corresponding colored port, i.e., yellow
connector to the yellow port, black to black, etc.
• The black lead is ground. Please ground this lead separately from the ground of highcur-
rent products such as power amps.
Do not ground more than one product together with the ground from another product.
For example, you must separately ground any amplifier unit away from the ground of
this unit. Connecting grounds together can cause a fire and/or damage the products if
their grounds became detached.
• When replacing the fuse, be sure to only use a fuse of the rating prescribed on the fuse
holder.
No ACC position
