Trim angle sensor connection
The trim angle sensor must be connected:
1.
Signal: connect the additional orange-blue wire labelled
"TRIM SENDER" to the extension cable, near the ECU.
2.
Ground: lead to a ground point of the electrical system,
possibly near the battery.
In the case of Mercruiser Bravo® stern drive connect the
sensor only to the instrument wiring, excluding other devices.

Connecting the trim/trailer control with
Mercruiser® mechanical throttle
The connection of the trim/trailer control to the Mercruiser®
mechanical throttle is not covered by this manual. For
information on connecting, refer to the installation manuals of
the drive and the Mercruiser® mechanical throttle.
The drive has a limit switch for the "LIMIT SWITCH" trim
operation that must not be confused with the "TRIM SENDER"
sensor. The limit switch, shoe in the following figure, is
connected to the throttle to control the trim.
