These connector breakout leads enable voltage readings to be taken from the numerous sensors and actuators in the engine compartment.
These connector breakout leads enable voltage readings to be taken from the numerous sensors and actuators in the engine compartment. The required connector breakout lead is simply connected into the existing cable loom, and the output signal can then be taken from the 4 mm banana plugs into the automotive oscilloscope using TA125 to TA128 premium test leads. The breakout cable has been designed with separate access to the individual wires to allow probing with current clamps. As an example this allows both injector current and injector voltage to be captured.
Note: the test lead is required to convert the 4 mm banana plug connection on the connector breakout leads to a BNC connector suitable for plugging into the PicoScope.
Connecting the connector breakout leads
Please read these instructions before using the connector breakout leads.
The signal pins must be identified by wiring diagrams or other means.
Regardless of the number of pins, Pico connector breakout lead colours are manufactured as follows:
- Pin 1 – Green
- Pin 2 – Red
- Pin 3 – Blue
- Pin 4 – Yellow
- Pin 5 – White
- Pin 6 – Black
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 will require it to be repaired at your own cost.
