6-way universal breakout lead, large (2.8 mm)

Designed to save you time and money

Pico’s universal 6-way breakout leads eliminate the need to own many specific breakout leads for engine diagnostics. The breakout leads are available with four different sizes of connectors, allowing you to connect to virtually any sensor in the engine compartment of many vehicles.

This product is a set of 6 large breakout leads as specified below

  • Length: 370 to 420 mm (approx. 14.5 to 16.5 inches)
  • Connector size:
    • large: 2.8 mm
In stock. Available for despatch.

How does it work?

Easy to use

The breakout lead is simply connected into the existing cable loom, enabling voltage readings to be taken from the numerous sensors in the engine compartment.

The output signal can then be taken from the 4 mm banana plugs to the input of the automotive oscilloscope using one of our premium test leads.

Connecting Pico Universal Breakout Leads

Please read these instructions before using the breakout lead. Pico Technology takes no responsibility for any damage caused through incorrect use. These leads are designed to be used by experienced/professional automotive vehicle technicians who understand the implications of incorrect use.

The signal pins must be identified using wiring diagrams or other means.

It may be possible to cause a short circuit to the oscilloscope unit if incorrect connections are made! A short circuit could seriously damage the unit, and would require it to be repaired at your own cost.

  • Ensure the ignition is switched off before removing any multiplugs
  • On removal of a multiplug keep the plug straight – do not twist the plug out of alignment with its mating partner
  • Always connect both the male and female terminals
  • The component-only terminals may be connected if carrying out a resistance test. Ensure the ignition is switched off during the test
  • Ensure each colour-matched pair of wires in the test lead is used to connect matching terminals in the male and female plugs
  • Never partially connect the test leads
  • Always ensure that the terminals are correctly located
  • Keep test leads aways from hot components, such as the exhaust system
  • Keep test leads away from moving parts, such as the alternator drive belt
  • Keep test leads away from electrical cooling fans

Typical Uses

Any measurement taken is only as good as the connection you make to the device under test. The 6-way universal breakout leads will connect to a multitude of vehicle components regardless of connector arrangement. This will ensure you have a 100% successful connection, removing any doubt from your test results. A broadband oxygen sensor test is a typical example where multiple measurements are required for both voltage and current. The 4 mm banana terminals introduce a simple and secure voltage measurement point for your test lead, whilst a current clamp can be applied to any breakout lead to monitor current. The breakout leads can also confirm the integrity of the harness/component "terminal tension" by inspecting for "grip" of the breakout lead terminal inside the vehicle connector.

  • Inspection of terminal pin contact for any matching connector
  • O2 sensor measurements for voltage and current (Including broadband)
  • Actuator measurements for voltage and current
  • Sensor measurements for voltage and feedback
  • "Open" and "short" tests of circuits
