I believe you can look up the manufacturer of the trailer plug kit and find the wiring diagram there. On alot of the trailer plug kits, they have pics and diagrams in the package. The 7 pin plug (truck side) is available with the pig tail set up that plugs directly into the wiring harness for the lights. Then all you would have to worry about is the 2 wires for the electric brakes.

If you are going from a 4 pin on your trailer to the 7 pin on the truck. You need to go to parts store or a department store (ex Wal Mart) and look in trailer section and find the adapter. Thats what I did. Also Remember if your lights don't work on trailer, check the plug to make sure its tight or check the fuse under your drivers side rear seat for that fuse box.

If you adding a trailer light harness, you can buy a seperate harness from most auto parts stores that will plug right in. There should be a connector near the rear of the truck that you can unplug, and add the trailer harness. It's simple and fast and you don't end up making a mess of your wiring. I suggest puting some "dielectric grease" on the connections to prevent corrosion.
Flat 4 connector.
Brown is tail lights and marker lights.
Yellow and Green are turn and stop. I think yellow is left.
White is ground.
