Been discussed in the forums many times. The only way to get the trailer wiring to work is to have it flashed by a dealer with a Chrysler Scan Tool. Nobody else can do it. $90 is the going rate. Not many dealers are going to do it for free unless you had negotiated it into your purchase price. It is basically 1 hour of shop time at many dealerships. Perhaps if you have some other work done at the same time (oil change, 15K maintenance, etc) they might cut you some slack since it actually only takes about 20-30 minutes to do the scan. Perhaps if you take it in and tell them you are having some other problems that require a scan for your build date, they will throw it in. Here is a list of TSB's:
Another reason to get the GC with the factory towing package, because by the time you get done with all the fussing around, it is going to cost you more than the $595 (2011-2013 model invoice pricing) or $795 for the 2014 V6 models.
They didn't have any that we wanted with a hitch at the time, at any dealer in the area. And the dealer wanted $800 to put one on it, after initially telling me $250. I know a lot of the guys on the WK2 forums have the cash to throw around, but I have a tighter budget to stick to, and it pisses me off when dealers feel they have to put the screws to everyone just because they can. So I'll go without lights until there's a cheaper option, it's a matter of principle to me. I mostly planned to use it with a hitch hauler anyway.
Correct, it's A 4 pin. They do have adapters to connect to 7 pin, but I don't tow anything with trailer brakes. If you plan on towing bigger trailers such as dump trailers, you need the chrysler kit and the flash.
thanks for the clarification on that obscure 7 pin reference.
Obscure? How do you tow a trailer and not know what a 7 pin connector was? I could see if someone doesn't know what a 5 way or 6 way connector was but almost all vehicles with a towing package come with the 7 pin connector instead of the 4 pin, although some vehicles are now coming with both 7 and 4 pins the eliminate the use of adaptors.
