Question:
OK, so i watched the video on installation on the 2008 Expedition. Which I have. But the video doesnt explain if you have to wire to a round 7 pin connector, which i dont have. Do you have anything that explains that? I would hate to buy your product without knowing how to hook it up.

For your 2008 Ford Expedition you would need a brake controller, the install harness, and a 7-way adapter to install the brake controller.
For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.
The install harness you need then is the part # 3035-P which plugs in under the dash.
Now with the 37185 there are a few more connections needed to be made at the rear of the vehicle.
Follow the 4-way trailer connector wires from the trailer connector to the front of the vehicle. These wires connect to a factory plug along the frame rail, usually on the driver's side, between the back tires and the rear bumper. The factory plug should be mated to another connector which has wiring that continues back toward the bumper.
There are more wires coming from the front of the vehicle than there are coming out toward the 4-Way plug. Run the blue wire here to the blue wire of the adapter.
