My 2005 Dakota drivers tail light is giving me problems. It recently has been cutting out and when I use the turn signal it does not work. The bulb out indicator light on the dashboard is on and the relay sound is fast when the directional is on. I have taken the light out, and taken the bulb holder socket out. The bulb is good, but I put a new one in anyway. I think the problem is the pigtail connectors. I can't seem to find the size that fit the male prongs on the socket. I can buy new sockets, which I am going to do, but where and what size are the female pigtail ends? Is this a dealer only part? I bought a connector kit but none of the provided connectors are the right size. They are all to big and will touch each other when pushed into the socket. I cut one half of the female connectors off to reduce the width but they are not tight enough to make a good connection and the result is sometimes the blinker works and sometimes it doesn't. This coincides with the illumination of the bulb out indicator on the dashboard. The bottom picture is of the plug showing the male connectors.

 

Moron Dealer...So, I go to the dealer, hoping they can help me out. Sure they can, new wiring harness they say. What? Can't find any option except replace the wiring harness. I ask, "well what would a tech do to fix it, don't they have some kind of electrical connection to repair it with" Moron says, "Tech would just replace wiring harness" Yeah, well the tech isn't paying for it. I told them in no uncertain terms to shove it. I would go to the Used Parts Dealership and do it myself, because, ALL cars run on used parts.
Later in the day I call and ask how much the harness is. They say $50 and change, I think, not much for a wiring harness. This guy though says that he cannot find the harness I was shown by the first guy when I was standing at the counter, the one that connects at the front of the bed and feeds the whole back of the truck. He says he has a harness that is just for the tail light and gives me the Mopar part #.
I get home, look up the part # on google and it takes me to Amazon Mopar parts section and lo and behold, it's the plug and pigtails.

I wouldn't want to be the parts guy when I show up tomorrow with the part number in hand, knowing it's in stock and tell him what a dumb___ he is for not being able to do his job and that he should maybe sweep floors or something that doesn't involve parts. Then I will find the GM and make sure the guy that can do his job and was able to restore my faith in the dealership receives recognition.

 

Had a buddy who had a similar issue where is turn signal would go off when he hit the brakes and that also was due to a corroded trailer wiring harness.

Then I had another similar issue with turn signals that turned out to be corrosion on the trailer hitch wiring harness as well.
