Automotive Breakout Leads – Sensor Voltage Measurement Leads for Oscilloscopes

These Automotive Breakout Leads provide a simple and reliable way to take voltage readings from vehicle sensors within the engine compartment.

The breakout leads connect directly into the existing wiring loom, creating a convenient access point for signal measurement. Output is provided via standard 4 mm banana plugs, allowing easy connection to oscilloscopes and other test instruments using suitable test leads.

This accessory is especially useful for diagnosing fuel injection systems, ignition components, and engine sensors, where direct probing is difficult or risks damaging connectors. The design supports fast setup during workshop diagnostics, mobile service work, and technical training.

Two different lead lengths allow flexible routing in tight engine bays, improving safety and measurement convenience.
