Not all trucks are built with a trailer harness plug. If you can not find one, then your truck does not have one and you need to install one.
Your local auto parts store can sell you a trailer plug harness that plugs into the vehicle's original harness that requires no cutting.
On the drivers side of the tail light there is a plug. Get up under the bumper and you will see a round plug and you have to do is unplug the plug from the light and plug in the wiring harness. The wiring harness will act like a patch and connects in about 15 seconds. Just make sure you have the right harness. The plug should be round.

Plug in the trailer harness into the 7 pin hookup next to the receive hitch if you have a stock towing package.
The way to plug in the harness depends on the type of harness that you have. Some are designed to unplug a connector then insert the harness inline with the wiring. Some require a special connector that clamps on the side of the wires, while others require wires to be cut and spliced together.
