My friend is a part time mechanic he gets his solutions from www.reliable-store.com he gets from their every single detailed info, instructions, diagrams, error codes, troubleshooting, transmission etc. everything on all vehicles, and factory manuals for service, repairs, parts, owner's, operations, maintenance etc.
U can get help from there
there is a girl at chat she can help you

The trailer plug wiring just taps into the truck harness to the rear lights so if the truck lights work, the problem is in the wiring, not a fuse.

Dark green with red wires the left stop turn signal Dark green with brown is the right stop turn signal Black with yellow is the tail lights.

You'll have to follow the BROWN wire from the factory connector(with the running lights on of course) to the trailer connector and make sure you are getting power all the way to the two lamp fixtures. If so you've probably got two burned out 1157 bulbs or an inline fuse in the factory harness/ trailer harness.Good Luck, Dana

there is no factory connector you must tap into the existing wiring for brake, turn signals, tail and running lights, they make special adapters to "piggy back" into these wiries, U-Haul trailer rental can do (install and sell) this kit for u very cheap.

for your trailer you need park light, brake light, left and right signal light. the best way is to tap them in the rear tail light wires.

You'll need to disconnect the wires from either the truck connector or the trailer connector...
I highly suggest purchasing a voltage checker- it looks like a screwdriver with a pigtail of wire with an alligator clip on the end. The tip of the 'screwdriver' has a point for probing. The light in the probe will light up...makes it easy to trouble shoot without a helper behind the trailer.
Hook the aligator clip to a good positive grounding point on the bumper or frame(not painted).
then pin by pin on the truck connection, stick the probe on each terminal tab.. and write a simple diagram where you find brake, tail, backup, etc...
Then i'd suggest, taking the connector off of your trailer, exposing the wire ends.
Run again thru your diagram and turn on each light of the truck. As you do, touch the wires from the trailer to that specific terminal. (make sure your ground wire is attached on the trailer) you can mark each wire with a piece of tape and label it which is which.
then simply attach your trailer wires according to your diagram to the terminals in the connector... that should get you in business..
hope that makes sense...
That way if the factory wiring harness remains the same, you'll be able to use it with other trailers if the need arises..

Get a tester light the type with an alligator clip and a sharp point.
Check each wire for your brake lights,blinkers etc.
i.e. With the blinker light on find the correct wire and splice into it with the corresponding light on the trailer. ( DO NOT CUT THE TRUCKS WIRE)
Remove the covering and twist the plug wires around it and tape or shrink wrap if you can.
Hope this helps

Is this a 4 way or 6 way connection system? If your truck is wrong, then all factory equipped trailer package harnesses would be wrong, tell your trailer guy...I don't think so.
Is this the first trailer you have hauled?
Let me know, and we will go from there.
