Wire & Switches: Use 18 AWG stranded wire on runs under 50’. For runs over 50’ use 16 AWG. Shielded wire is recommended for
all Diesel systems and suggested for Inboard & I/O gasoline systems. Always, “Ground” the wire shield or shield drain wires in the
engine room by connecting them to the bonding system or engine block. The double wiring harness for twin engine Pulse/NMEA
Diesel installations is included in all, (97/9800(0)) kits. FloScan suggests using J-Boxes, Terminal Blocks, and three conductor cables
between diesel sensors and instrument to make wiring easier.
Install Single Pole Single Throw (SPST) switches for Totalizer Reset, Port–Starboard Select, Engine Hours / Synchronizer, and GPH /
MPG, (switches are not included with kit). To determine which switch types are required for your system, refer to the table below. All
instruments except TwinScan
Tachometers require a totalizer reset switch.

Grounding: Each Black sensor wire must be connected directly to the Black, “Instrument Ground” wire. Use a single wire to connect
the Black wire junction to the battery’s negative terminal, or a ground buss.
Power: FloScan Instruments & sensors operate on 9 to 12 VDC. Voltages exceeding 16 VDC will damage equipment. 24 & 32 VDC
systems must be reduced to 12 VDC. Two different types of voltage reducers are available through FloScan.
WIRE CONNECTIONS
Installation: Connect wires one at a time and install heat shrink tubing before proceeding to
the next wire, (refer to diagram). Connect ground wires first, (BLACK instrument ground
wire to the BLACK sensor wires). Connect this junction to the battery’s negative terminal
or the ground buss. Connect all other wires leaving the Red power wires for last to prevent
short circuits during installation.
Splicing: Splice or join individual wires per the diagram. Slide heat shrink tubing over the
splices to prevent shorts. Do not seal splices until the installation is finished and has been
tested.
An adequate number of crimp-on connectors and heat-shrink tubing are included with
system. The heat-shrink is a special type that will bond to wire insulation and make a
watertight connection. See diagram for proper tubing application. Crimp-on connectors are sized for 18 or 20 gauge stranded wire.
1. Slide heat shrink tubing
over one wire.
2. Insert wire ends into butt splice.
3. Crimp butt splice.
4. Slide heat shrink tubing
over butt splice.
5. Apply heat.
