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
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.

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.
