FIFTH
WHEELS

1

1. Sensors are installed on the fifth wheel at Holland
Hitch Company: Remove the existing Holland fifth

wheel and replace with the Electronic Lock
Indicator-equipped fifth wheel.

2. Install the display box in the cab: Mount the
display box in an area of the cab that is easily
visible and accessible to the driver. Clean
the display box mounting surfaces with
isopropyl alcohol and allow to air dry. Use the
adhesive-backed reclosable fastener provided to
attach the display box to an appropriate surface.
Route the cable coming from the display box
inside the cab where the socket end of the 25´
foot cable will be located.

3. Install the corrugated loom
around the 25´extension cable.

4. Cut one slit into the
grommet. (See FIGURE 2.)

5. Wrap the grommet around the
25´ extension cable in the approximate location
where it will enter the cab. (See FIGURE 3.)

WARNING

The electronic lock indicator is a tractor/trailer fifth wheel coupling aid and is intended
as an additional safety check to assure the driver of a safe and complete coupling.
It does not eliminate the requirement for a visual inspection of the fifth wheel.

ALWAYS GET OUT OF THE TRACTOR CAB AND VISUALLY INSPECT THE FIFTH WHEEL COUPLING!

INSTALLATION PROCEDURES continued

6. Drill a

13

/16˝ diameter utility hole in the cab
making sure that there are no obstructions
near the drilling area.

7. Run the end (A) of the extension cable with the
power wires (see FIGURE 1), through the utility
hole and into the cab.

8. Install the 1-amp fuse (see FIGURE 4):
a. Strip 3/8˝ of insulation from the RED

extension cable power wire and from
the tractor’s positive (+) power wire. It is
recommended that a switched terminal in
the main fuse box be used so that power is
supplied when the ignition is turned on.

b. Insert the wires into each end of the

fuse holder.

c. Crimp each terminal through the fuse

holder body.

9. Connect the two power wires from the 25´
extension cable to a 12- or 24-volt power
supply. (The back of each display box is
marked with 12- or 24-VDC.) Be sure to
connect the RED wire with the fuse —
as outlined in STEP 8 — to the positive (+)
terminal, and the BLACK wire to the ground
(-) terminal.

10. Connect the 25´ extension cable to the
ELI display box cable inside the cab.

11. Press the grommet into position in the utility
hole. Apply sealant to the grommet and
extension cable to prevent moisture intrusion
into the cab.

12. Route the 25´ extension cable from the cab to

the fifth wheel. See FIGURE 5.

13. Route the wire clear of pinch points.

NOTE: For sliding fifth wheels, be sure to leave

enough slack for travel and route the
wire clear of pinch points. It can be
helpful to route the wire through an
existing coiled air line.

14. Secure the extension cable so that it is free of
interference from the fifth wheel articulation,
brake lines, light cord, drive line etc.

15. Remove and discard the protective plug from
the connector at the end of the fifth wheel
sensor harness as shown in FIGURE 6.

16. Connect the 25´ extension cable to the sensor
harness on the fifth wheel.

17. Check the operation of the fifth wheel and the
Electronic Lock Indicator using lock adjustment
tool TF-TLN-5001.

For operating instructions, see Holland publication
XL-FW389-XX.
