I bought it from dodgeparts.com, it had a long wire like you mentioned and a clip in the parts bag that matched up to the plug behind my A pillar. i trimmed the wire to the correct length and put the clip onto the wire and I was done. The clip was not listed as a part so I may have gotten lucky, I do not know. The instructions showed you to feed it to the fuse block like you mentioned but I had read in a post a day or so ago about the plug behind the A pillar and I had one there so I tried it out and it worked. Dumb luck I guess for me cause the instructions of feeding it through to the block looked like a mess.
