A. 36 poles connector - A1. 16 poles connector -
A2. 89 poles connector.
The connection of the central electronic unit, ECU, to the
components of the EDC system is achieved by means of
three connectors to subdivide the wiring harnesses, thereby
favoring a quicker identification of the lines during testing
operations.
The different connectors are polarized and provided with
levers to favor the connection and disconnection operations
and assure proper coupling.
They are dedicated to the following functions:
❏
Connector A for engine mounted components
❏
Connector A1 reserved for electro-injector connection
❏
Connector A2 for boat side connections
