PICO TA191 3 Pin Breakout Lead

The Pico TA191 connector breakout lead enables you to take voltage readings from the numerous sensors and actuators in the engine compartment. Simply connect the breakout lead into the existing cable loom, and then connect the 4mm banana plug of your test lead to the breakout leads banana jack. The breakout cable gives access to the individual wires to allow probing with current clamps. For example, this allows both injector current and injector voltage to be captured.

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
