Things You'll Need:
- 4 pin connector or 5 pin connector
- Wiring cable
- Electrical Tape
- Wire connectors
- Screw Drivers
- Drill

Step 1
Determine the connector required. Four pin connectors provide for basic lighting function: Stop, left and right turn. A five pin connector covers all the basic functions plus allows for brake signal or auxiliary power.
-
Step 2
Calculate the amount of wiring cable you need. Remember to take into account the fact that the wire will need to run from the vehicle and allow enough slack for turning.
-
Step 3
Map the wiring path out on paper. The green wire is for, right turn signal & stop light, yellow is left turn signal & stop light, brown is taillight, license & side markers and the white is for grounding. On a 5 pin (blue) is for auxiliary power.
-
Step 4
Run the wiring and secure it underneath the trailer. Use zip ties to secure the wiring by wrapping the tie around the frame. Make sure to use a color tie that matches your trailer to provide a nice clear look.
-
Step 5
Attach the ground to any bare metal area, like a bolt or screw on trailer.
-
Step 6
Connector the wiring to the trailer lights. Use electric tape or wire connectors to secure the wiring.
-
Step 7
Connect the trailer to a vehicle and test the lights, by stepping on the brake, turning on the left and right turn signal to make sure the lights are working properly.
