Question:

I have a 1999 dodge 2500. It did not come equipped with the factory tow package. I need the 7 blade connector as well as trailer brake controller. What do you recommend? Thanks

Hey Cory, thanks for reaching out!

I'd be more than happy to help you get your 1999 Dodge Ram 2500 set up for trailer towing! Here are the parts you'll need:

- T-One Vehicle Wiring Harness # 118329
- Universal Wiring Upgrade # ETBC7
- Mount Bracket # 18136
- Prodigy P2 Brake Controller # 90885

The T-One tees in behind your taillights and then the ETBC7 wiring comes with everything you need to get a fully functioning 7-Way and additional wiring to make sure your brake controller is installed. And then I really like the Prodigy P2 controller because it is a tried-and-true controller that's just straight-forward and easy to use.

I've attached some installation videos as well as a helpful article we've written about installing a brake controller from scratch on a Dodge Ram truck in your model year range.

Let me know if you end up having any other questions!

Thanks for the reply- the brake controller says out of stock until May 15, is that correct? I can’t wait two months. Thank you!

@Cory Oh wow, I didn't even realize the date was that far out! In that case, I recommend checking out the Prodigy P3 # 90195 which is just the next version of the Prodigy lineup and comes with a few extra settings.
