Installation sequence (interface input. alt 1)
1. Connect the control system harness to the
interface (1) screw terminal as illustrated and
described in the table.
note! The specified input signal levels are re-
quired for the interface to work correctly.
2. Connect the interface to the 12-pin connec-
tor on the HCU, as described in alt 1.
note! Secure the interface in a suitable loca-
tion, using a tie wrap or screw.
3. Carry out an auto-configuration of the sys-
tem. For further information, refer to the EVC
installation manual.
Diode indication, interface input:
throttle control, diode indication (a)/
trolling, diode indication (B):

Other cases.
Installation sequence (interface output. alt 2)
1. Connect the Y connector (2) between the
PCU and the engine, as illustrated.
2. Change the interface baud rate by bridging
screw terminal connections 9 and 10.
3. Connect the interface to the 12-pin connec-
tor on the Y connector, as illustrated.
note! Secure the interface in a suitable loca-
tion, using a tie wrap or screw.
