Wiring & Installation Guide

1 Check Your Existing Connector
If the original vehicle-side connector does not match the receiver's plug, do not force it. The receiver is designed for a splice-in installation. Cut off both the receiver's connector and your original connector, then join the wires directly.
2 Splice the 2-Core Wire +
The receiver uses a simple 2-core cable. There is no positive or negative polarity, connect each wire from the receiver to the corresponding wire on the vehicle harness. Use crimp connectors or solder and heat-shrink for a reliable, long-lasting join.
3 Understand NC vs NO +
This receiver is NC (Normally Closed), the circuit is closed (made) when the buckle is at rest. When you insert the tongue, the switch opens, telling the vehicle the belt is fastened. This is the "alarm ON" configuration: your dash warning light will illuminate if the belt is not buckled. If your vehicle requires an NO (Normally Open) receiver, choose the alarm OFF variant instead.
4 Mount and Test +
Bolt the receiver stalk to the seat or floor mounting point using the original bolt (or a suitable replacement). Before final tightening, test the buckle engagement and verify the dash warning light behaves correctly. Once confirmed, torque the mounting bolt to the vehicle manufacturer's specification.
