Gator Tuff Tip Oct '12

Trailer Wiring

Trailer wiring schemes can vary according to manufacturer.  However, there are many common schemes among manufacturers.  Be sure to consult your manufacturer’s specifications before wiring any trailer.  If wiring from scratch, be sure to choose a wiring scheme and adapters with the correct number of wires and posts to outfit the number of applications that you use.

Wiring Schemes

Your white wire is typically the ground in most trailer wiring schemes.  Brown is usually for tail and marker lighting, green for passenger side stop and turn lights, and yellow for driver side stop and turn lights.  Below are the wiring schemes used by Gator Made technicians:

       4 Way Blade Plug Trailer End                                        7 Way Blade Plug Trailer End
                                                                                       (View from back of plug where wires attach.)

When wiring multiple lights, using quick splices is an advantage, where creating wiring unions is, otherwise, can be difficult.

     Make sure that all connections are secure and no wires remain bare.  Make sure there is not too much slack in your wiring and wires are not in the way of, or tangled around moving parts of the trailer.  This will assist in keeping wires and connections from becoming disengaged or being broken by moving parts  and, also, outside environmental factors.
      Once you have finished, make sure to inspect and test your wiring and connections thoroughly.  When wiring a trailer, be sure power sources are not connected to the trailer, follow all other necessary safety practices, and be sure to check the regulations of the DOT.
