ELECTRICAL
Series 9000(0) NMEA Input, Gasoline Multifunction Instrument
Port/Starboard Select Switch: Twin engine operation requires a Single Pole Single Throw, (SPST) switch. The select switch allows
you to display RPM & GPH readings for either PORT or STARBOARD engine. Connect one side of the switch to the BLUE wire
from pin #11. Connect the other side to the Black wire on pin # 13. The MFI displays Port readings when the switch is open, Starboard
readings when closed.
GPH/MPG Select Switch: MPG operation requires a Single Pole Single Throw, (SPST) switch. The select switch allows you to
display either GPH or Nautical Miles per Gallon. Connect one side of the switch to the GRAY wire on pin #2. Connect the other side
to the Black wire on pin # 13.
Totalizer Reset: The instrument requires a Single Pole Single Throw, (SPST) to reset its Totalizer, (Gallons or Liters Window).
Either a momentary ON or standard ON/OFF switch can be used. To reset, close or turn the reset switch ON and hold for
approximately 15 seconds. Once cleared open, or turn the switch OFF for normal operation.
Engine Hour Meter: The engine hour meter can not be reset.
Engine Synchronizer: On twin installations the HOURS window can be adapted to function as a synchronizer display. To operate as
a synch display a Single Pole Single Throw ON/OFF switch must be connected between the White/Yellow wire on pin # 3 and the
Black wire on pin # 13. Refer to the Wiring Diagram.
Illumination: Connect the Orange wire from pin # 4 to illumination circuit, or to a 12 VDC power source.
Tachometer Wiring: For proper tachometer operation on EFI engines, (especially outboards) the engine Ground wire must be
directly connected to the MFI instrument ground wire. FloScan recommends using dedicated 18 AWG shielded cable for tachometer
signal wire connections. Always, “Ground” wire shield or shield drain wire in the engine room by connecting it to the bonding system,
or engine block.
CARBURETOR & CLOSED LOOP EFI GASOLINE ENGINES with POINTS or STANDARD ELECTRONIC IGNITIONS
Inboard, & I/O Engines: Connect the Yellow wire from pin # 8 to the distributor coil’s negative terminal. On twin engine systems the
Yellow wire from pin # 8 connects to the port engine, the Violet wire from pin # 16 to starboard.
Outboard Engines: Outboard tachometers are connected to either the engine alternator or tachometer signal wire. Connect the
YELLOW wire from pin # 8 to the engine alternator or tachometer signal wire. On twin engine systems the Yellow wire from pin # 8
connects to the port engine, the VIOLET wire from pin # 16 to starboard.
CLOSED LOOP EFI GASOLINE ENGINES with CPU IGNITION SYSTEMS
Inboard, I/O, & Outboard Engines: Connect the Yellow wire from pin # 8 to the engines’ tachometer signal wire. On twin engine
systems the Yellow wire from pin # 8 connects to the port engine, the Violet wire from pin # 16 to starboard.
Outboard Engines: Connect the Yellow wire from pin # 8 to the engines’ tachometer signal wire. On twin engine systems the Yellow
wire from pin # 8 connects to the port engine, the Violet wire from pin # 16 to starboard.
CHRYSLER (Except Magnapower I) - Connect tachometer signal wire(s) to the engine terminal strip marked, “ALT”.
JOHNSON/EVINRUDE/SEADRIVE - Connect tachometer signal wire(s) to the gray wire at key switch harness or Gray/Yellow
alternator wire on engine terminal strip. For 1984 and later model years with standard voltage regulators, connect the tachometer
signal wire(s) to either the Gray voltage regulator wire, or the Yellow/Gray alternator wire on the engine terminal strip.
MERCURY/MARINER - Attach tachometer signal wire(s) to the Yellow/Red, or Yellow wire terminal on engine rectifier.
SUZUKI - Remove three screws from rear of the throttle control box and remove cover plate. Attach tachometer signal wire(s) to the
Yellow wire, and shield ground wire to Black wire. Keep wires away from the moving parts in control box and reinstall back cover.
YAMAHA - Attach tachometer signal wire(s) to the Green wire, and shield ground wire to the Black wire at underside of shift control
box. If the Green wire is not accessible at control box, either Green wire on engine terminal strip can be used.
