Verify Compatibility Before Purchase
Confirm truck model, year, and electrical configuration (e.g., single vs dual battery).
Some variants have different terminal types (stud vs ring).
Professional Installation Required
Involves connecting high-amperage cables directly to batteries.
Must be performed by trained technician using proper tools and safety gear.
Use Correct Cable Size
Install with appropriate gauge wire (typically 25–35 mm²) to prevent overheating.
Secure connections tightly to avoid resistance and hot spots.
Ensure Proper Grounding
Clean contact surfaces and apply anti-corrosion grease to terminals.
Loose or corroded grounds cause system failures.
Follow Correct Operating Sequence
Always stop engine before turning OFF the master switch to protect alternator from voltage spikes.
Turn ON switch first before starting the engine.
Mount in Dry, Accessible Location
Install near battery box but protected from direct water spray and mud buildup.
Avoid placing under fuel lines or exhaust components.
Check Control Signal Wiring
The cab-mounted activation switch sends a low-voltage signal — ensure this circuit works properly.
Test remote function after installation.
Inspect Regularly
Corrosion at terminals
Loose bolts
Burn marks or discoloration
Check every 50,000 km or quarterly for:
Replace immediately if damaged.
Do Not Bypass the Switch
Never "hot-wire" around the switch — compromises safety and may void warranty.
Storage Advice
Keep sealed in original packaging until use.
Store in dry indoor environment away from moisture and extreme temperatures.
