Connection Diagram of SPST Switch (sold separately)
• If your vehicle has no ACC power supply, add an SPST (single-pole, single-throw) switch (sold separately) and fuse (sold separately).
• The diagram and the fuse amperage shown above are in the case when the unit is used individually.
• If the switched power (ignition) lead of the unit is connected directly to the positive (+) post of the vehicle’s battery, the unit draws some current (several
hundred milliamperes) even when its switch is placed in the OFF position, and the battery may be discharged.
