3). Possible locations of connectors and sensors
To connect the Multitronics CL-950E to the diagnostic connector of the engine, refer to the manufacturer's technical
documentation or to a technician experienced with these types of engines.
As a rule the diagnostic connector is located next to the engine control unit (ECU) under a protective cover against
moisture and dirt.
The schemes below show the locations of diagnostic connectors and sensors for some types of engines from various
manufacturers.

The "trim" wire must be connected to the signal wire (see the
electrical diagram for the engine. In most cases you can determine
the proper wire using a tester: one of the wires is the ground, on
the second (signal) the voltage varies depending on the position of
the engine. The example on the right demonstrates that B is the
ground (black) and P is the signal (pink).
Connect the "injection plug" wire to the signal
wire (see the electrical diagram for the engine).
As a rule it is possible to determine the signal
wire by color as each plug is assigned to its own
color whereas the common wire has the same
color for all plugs. In the example diagram above
the signal wires are blue, purple or green whilst
the white-red wire is the ground.
