-
Harnesses are internally grounded
- so trailer corrosion doesn't effect circuit continuity. Not
grounded through trailer frame. Both negative and positive
leads are directly wired to each light from the vehicle.
-
Plugs filled with non-conductive
corrosion inhibiting grease
-
Not affected by rust or wet
conditions.

Grounding through trailer frame means
electrical continuity is affected by rust and elements.
Lighting/Wiring issues is one of the number 1 problem trailer
owners experience. These are exasperated by rust inhibiting
the connections at the main grounding point and each light's ground
point, which is the bolt connecting it to the trailer frame.
Electricity must run from the vehicle through the metal trailer
frame and all the connections must be rust free.

-
Molded connections between
modules keep moisture and contaminants from penetrating the
electrical system.
-
All modules filled with
non-conductive corrosion inhibiting grease.
-
Wires are molded into a
protective outer casting.
-
Main harness 14 ga. wire.
-
Harness is run inside the
frame tube to protect from elements.
|
-
Flat four wiring has very little
protective insulation which can easily be penetrated by flying
road debris or worn through from vibration.
-
Some manufacturers incase the
wire in split loom, but it isn't designed to protect against
outdoor elements and moisture.
-
Some use conduit, but all connections
made outside of piping.
-
Weak wire connections are done
with crimp connectors or splice and tape. Elements and
road vibration wreak havoc with these types of connections.
-
Most wishbone harness use 18 ga.
wire.
-
Run on underside of trailer. Wire
is exposed to elements and road debris.
