TVMSDBWK‑002
Water Tank Sensor Wiring Loom
The TVMSDBWK range allows the RedVision Total Vehicle Management System (TVMS) distribution box to
measure the water level in an RV/motor home clean water tank. If installing this kit for a gray or black water tank,
refer to the TVMS1280 Instruction Manual for further information.
The TVMS can report five states: empty, one-quarter, one-half, three-quarters, and full. The TVMS can measure
the level of up to six tanks. A separate TVMSDBWK-001 is required for each tank. For more information, refer to
the RedVision Instruction Manual available on the REDARC website.
TVMSDBWK-001 includes all parts. TVMSDBWK-002 contains only the Wiring Loom.

1. MEASURE AND MARK (TVMSDBWK-001 Only)
CAUTION
Any Sensors positioned close to corners of the
tank must be at least ½" (12.5mm) away from the
curvature of the tank, i.e. The centre of the probe
must have a radius of at least at ½" (12.5mm) of
flat surface to mount on.
½"
(12.5 mm)
On the side of the tank, measure out the Sensor
positions, starting with the top Sensor at the 80%
mark, then 60%, 40%, and 20%. Position the
bottom Sensor as close to the bottom of the tanks
as possible — Note that this means that the spacing
between the Sensors may not all be equal.
Note: the Sensors do not have to be mounted in-line.
The example shown ('Front' view) is acceptable.
Before drilling, check each marked location for good
access and confirm face is flat both outside and inside
at least 1" (25mm) around each position.

2. DRILL (TVMSDBWK-001 Only)
Ensure tank is empty of liquid before drilling holes.
Using a sharp 3⁄8" (or 9.5mm) drill bit, drill each marked location at
slow speed. Ensure the cut is clean (de-burr inside and out) as any
irregularities will prevent a good seal.
Note: Using a drill bit greater than 3⁄8" (or 9.5mm) in diameter may
prevent the Sensors from sealing properly, resulting in leaking.
3. INSERT SENSORS (TVMSDBWK-001 Only)
For each Sensor,
remove the top nut.
At each location, gently push the Sensor
through the drilled hole until the rubber
stopper is flush with the outer tank
surface.
Tighten the nut to form a waterproof seal
(the rubber is squeezed against the inner
wall). Torque to 0.5 lbf-ft (0.7Nm)
INSTALLATION

4. WIRING
Connect the supplied Wiring Loom to your TVMS system (as detailed
in the product user manual), and run the cable to the tank.
Optionally, the cable length can be reduced if required. Terminate
each wire using the supplied Crimp Lugs. Crimps can be soldered
after crimping for a more reliable connection but is not required.
To reduce strain from vibration on the wires and to avoid accidental
shorting, we recommend applying heatshrink (not supplied) to the
crimped wires/lugs.
For each Sensor, slide on the crimped Lug and secure with the
second nut. Torque to 0.5 lbf-ft (0.7Nm) while preventing the nut
closest to the tank from rotating.
Wire colours:
• 80% (top) — BLUE wire
• 60% — WHITE wire
• 40% — GREEN wire
• 20% — YELLOW wire
• Empty (bottom) — RED wire
5. SECURE THE LOOM
Secure the Wiring Loom to the TVMS mounting
surface approximately 3" (100mm) from the
connector. Suitable options include a P-clip or cable
tie fastened to the mounting surface.
This is to reduce vibration on the connector to
prevent damage to the connector and unit.

CLEAN WATER LEVEL REPORTING
The approximate tank level is reported by the RedVision App
(Smartphone app or TVMS Display).
