⚠️ TANK 300 / TANK 330 PLATFORM CRITICAL TECHNICAL INSTALLATION NOTICE

• Strict No-Load & Shipping Tie Warning: Never connect power to actuate or bench-test the system before the upgrade kit is completely bolted into the door framework. Running the system under zero-load conditions can permanently warp the lock mechanism. Ensure the shipping cable tie on the lock tongue is cut off before assembly.
• Sponge / Foam Strip Removal Required: Carefully inspect the OEM factory lock block. You MUST completely peel off the black factory sealing sponge/foam layer from the contact surface. If left intact, the sponge will bunch up inside the upgrade latch mechanism, creating immense mechanical friction that causes motor return or suction cycle failure.
• Bracket Tab Alignment: When integrating the upgrade lock unit with the custom-molded mounting bracket, make sure to slide the bracket tabs firmly into the designated lower slots. Ensure it does not slide out of alignment toward the upper frame before securing the screws.
• 无损对插取电 Window Lifter In-Line Interception: Power routing for the side doors is fully localized. Unplug the factory wire harness connector from the power window lifter motor, and insert the LiTanglee inline T-Harness adapter directly between the factory socket and the motor to safely intercept fused 12V power.
• Chassis Grounding on Body-on-Frame Architecture: Due to the heavy-duty non-bearing (非承载式车身) structural design of the Tank series, the black system ground (GND) wire must be secured directly to a main structural metal chassis grounding bolt inside the door framework. Avoid loose grounding on internal plastic modules or secondary wire taps to ensure absolute voltage stability.
• Off-Road Deep Cavity Glass Clearance Pre-Test: Due to the rugged, square door geometry of the Tank 300/330, you must completely roll down the window glass manually after mounting the kit to visually verify that the descending glass frame safely clears the newly upgraded motor housing and suction bowden cables inside the door cavity.
• Rugged Weatherstrip Striker Adjustment: The Tank series employs ultra-dense, multi-layered rubber weatherstripping for advanced off-road dust and water isolation. If the secondary suction pull stops halfway or experiences excessive compression resistance, loosen the vehicle chassis door striker bolt slightly and move it outward by 0.5mm to achieve a fluid and effortless soft-closing cycle.
• Tailgate Heavy-Duty Load Specification: The rear side-opening cargo tailgate holds a heavy spare tire. When installing the Tailgate Soft Close module, ensure the motor actuator cable curves naturally without sharp bends behind the rear panel liners to prevent any long-term structural strain under off-road vibrations.
