The black surface mounted plug next to the hood release is the ODBII connector for diagnostics.
Yes the arrow points to the correct plug. Most of the name brand brake controllers have a double ended plug. One end fits the controller the other fits the plug under the dash. For the Tekonsha products (Prodigy) the part number is Tekonsha 3045-P. This is the same one that is used on the 2011-2014 Grand Cherokee.
