First, check underhood to see if you have the relays in the spots reserved for trailer brakes etc. I'm pretty sure the old connector will hook up to the new truck one under the dash there. If not, the dealer will have one. As far as the 7 pin, I went to the dealer and got a 7 and 4 pin combo with bracket, it will plug into the connector same as the 4 pin along the frame and into the taillight plug. That's the easiest way but not only. A universal one comes with bare wires you'd need to solder together matching colors etc. You can also use crimped connectors. Then you should be set.
