I take it NAPA isn't sure so I am glad you came to us. It looks like the controller you bought is either the original Prodigy or the P2, # 90885. But the wiring harness does not look like the correct one. You need # 3023-P.

Ram started a new electrical system they call the PowerNet which is a multiplex system. It is more complicated than what came before it so a special wiring harness had to be developed.

I have included a link to the right to a video that shows how to install a controller on a 2013/2014 Ram.
