An electric brake controller is an option but it is not part of the tow package. If you look around here and on other forums you'll find that some people have problems with the factory brake controller, even to the extent that they replaced it with aftermarket ones. So non-factory appears to be the way to go. Tekonsha and maybe others have wiring harness adapters which make installation plug and play.
First I've heard of any issues.
I've towed fairly regularly with my Ram over the last 2 1/2 years and never had an issue with the factory controller. Works great.
It's a must have option in my opinion.
To the OP:
The factory brake controller is an optional item, but I don't think it automatically comes with the tow package. Could be wrong there.
If you decide to go with aftermarket, I had a Prodigy in my last truck that worked really well.
The Tekonsha P3 is supposed to be a really good unit, but it's a bit pricier.
