what he said. that is the OBD port.
On my 05 Ram the plug (which BTW is 4 pin) was way up the left side above the parking brake all the way to the firewall. I had to put my head under the brake pedal to see it. I also had to run the adjustable pedals all the way out to get my hand back there as the rack and motor for that system was in the way.
Note: unless you truck came with trailer tow group, the plug may not be there. You should check with the dealer on it, they can run your VIN to tell you what groups were installed. They can also sell you the pigtail, though Prodigy also sells a truck specific plug for all their products.
