Mounting Instructions

Mounting Hole Pattern Detail
Monitor Housing
The FloTech model FT204 Retain / Overfill Monitor Housing is
typically mounted on the trailer main frame rail, fitting storage
box, or any flat surface within easy view of the bottom loading
connections. Leave the top cover on the monitor housing and
hold it in the position you wish to mount it. Using a black
marker, transfer the pattern of the four mounting holes to the
mounting surface. BEFORE drilling, check to make sure you
will not drill through or damage any existing trailer wiring or
piping. Drill the holes through and mount the monitor using
four 3/8 inch nuts and bolts.

Cable Installation Instructions
FloTech recommends you use FT401 jacketed 7-conductor
cable when wiring a new system. This cable is specially
designed to be oil, UV, and abrasion resistant. It incorporates a
noble tin-plated stranded copper wire which resists corrosion.
When installed properly, this cable will provide years of reliable
service.
See the Proper Wire Connections section for more detailed
directions about stripping and terminating the cables.
Monitor Housing
After the monitor housing is mounted, install FloTech FT402
cable glands in the openings where needed. These are, as
illustrated in Fig 3. : Power, Overfill Sensors, Retain Sensors (if
equipped) and Socket. Route the lengths of FloTech FT401
cable through the conduit openings. Cut the cables to length
leaving approximately 8 inches of extra length inside the
monitor housing.
Unused conduit openings in the sensor housings must have a ½
inch NPT pipe plug installed. Note that when using the
FloTech FT390 Dual Socket Assembly, you only need to install
one cable gland for the socket wiring.

Wiring Instructions
Proper Wire Connections
Please read this section of the manual before attempting to wire
the FloTech FT203P Monitor. This section recommends some
„guidelines‟ for installing the system wiring that, when done
properly, will insure a long, trouble free service life for your
equipment.
CABLE STRIPPING
FloTech recommends using FT401 seven conductor cable to
wire the Onboard Monitor System. When stripping the rubber
jacket from the cable, FloTech recommends using the FT9023
or equivalent Cable Stripper. This stripper has an adjustable
cutting blade depth setting. The depth should be set to only cut
through one-half to two-thirds of the outer jacket thickness.
This will insure that the insulation on the inner conductors is
not nicked. Any nicks or cuts in the wire insulation can, over
time, degrade the quality of the wire and lead to intermittent or
total failure.
BUTT SPLICE CONNECTIONS
FloTech recommends using the FT9022 or equivalent Crimp
Tool for securing the Butt Splice connections. Follow this
process to secure each connection:
1. Follow the Cable Stripping instructions in the previous
paragraph to expose the individual conductors of the
wire.
2. Strip the insulation back on each conductor
approximately ½ inch. Take care not to cut off any
strands of wire. If too many strands were accidentally
cut off, cut the wires flush with the insulation and strip
again.
3. Hold the two wires to be connected together by the
insulation. Tightly twist the bare wires together. This
insures a good electrical connection.

4. Fill a FloTech Butt Splice with Silicone RTV
compound. Insert the twisted wires into the filled splice.
Check to see that the bare wires are fully inserted into
the splice and RTV. Make certain that NO bare wire is
protruding from the splice.
5. Securely crimp the wires into the butt splice.
6. Give the splice and the wires a „tug‟ to make sure you
have a good mechanical connection.
TERMINAL BLOCK CONNECTIONS
Follow this process to secure each connection:
1. Strip approximately 3/8 inch of insulation back from the
end of the wires.
2. Tightly twist the strands of wire together.
3. Rotate the terminal block screws counter-clockwise a
few turns to relieve pressure on the wire retainer.
4. Insert the bare wire end into the terminal block.
5. While holding the wire in place, rotate the terminal
screw clockwise to tighten the wire retainer.
6. Once fully tightened, give the wire a slight „tug‟ to
insure that a proper connection has been made.
Monitor Wiring Connections
Before attaching wires to the FT203P Monitor, please read the
following:
CAUTION: Turn off or disconnect power to the trailer before
wiring the monitor.
CAUTION: Only use the conduit opening marked “POWER
INPUT” as shown in Fig. to wire power to the monitor.
CAUTION: The FloTech FT203P Monitor will NOT work on
POSTIVE GROUND electrical systems. Any attempt to wire
the monitor to a positive ground system will damage the
monitor and void the warranty.

TB1 POWER Connections
Refer to Fig. 4. FloTech recommends routing the trailer power
through a weatherproof inline fuse holder containing a 1/2 amp
fast blow fuse to the monitor. Optionally, a switch can be
added in series with the fuse to the TB1 input. Connect the
positive power supply wire to the TB1 terminal marked “12/24
VDC”. This is the upper screw on TB1. Be careful that no
stray wires are touching the metal barrier or ground terminal.
The Power Ground wire connects to the TB1 terminal marked
GND.

TB2 TOP and BOTTOM SENSOR Connections
FloTech recommends wiring the sensors to the FT203P Monitor
using FT401 seven wire cable using color code shown in Fig.5.
Complete wiring schematic is shown in back of this booklet.
