5. Apply two wire ties to the splice. The first goes over the splice and the other approximately one inch
down the line of splice.
2-wire versus 3-wire installation
Determine whether you are doing a 2-wire or 3-wire installation. The Reveal Hardware Installer app will
ask you to select one or the other. The 2-wire method is typically used on trailers while the 3-wire method
is typically used on heavy equipment “yellow iron” assets such as backhoes and bulldozers.
2-Wire installation steps
1.
Connect the device’s red wire to the asset’s +12/24V constant power source.
2.
Use a ring terminal to connect the device’s
Black
Ground
wire to the asset’s negative battery
terminal
or
use a self-
tapping screw and a ring terminal to connect the device’s black ground wire to a
chassis ground.
3. Coil up and zip tie any extra length of the device harness.
Do not cut the harness
to shorten it, as
doing so limits the device’s usability if transferred to another asset in the future and also increases the
chance of making an error with wiring.
2-Wire installation for nose-mounted semi-trailers using a 7-way connector
1. Remove the 7-
pin connector’s mounting plate.
2. Mount the unit to the trailer using provided mounting hardware.
3. Use an existing pass-through hole or, if one is not available to use, drill a new pass-through hole into
the trailer skin. If it’s a new hole, pull the harness through a grommet.
4. Push harness end down interior side of trailer wall toward the 7 way connector.
o
If it will be necessary for the harness to pass through, clip off the preinstalled fused links from
the device harness.
o
Make a drip loop in the harness to prevent condensation from running towards electrical
connections.
o
If a grommet is used, insert it into the pass-through hole. Apply a bead of silicone around the
grommet to seal the pass-through.
5. Pull the wiring harness through at the 7 pin connector.
6. Reattach the fused links using heat shrink butt connectors, and verify a 3-5 amp fuse is present.
7. Separate the black and red wires from the harness.
o
Tape any unused harness wires to the harness sheath (do not cut to custom length).
8.
Connect the device’s black ground wire to the trailer’s white wire/top pin on the 7-way trailer stud
using a heat shrink ring terminal or poke-and-wrap method.
