Question:
I’m looking for a trailer brake controller for my 2007 dodge ram 3500. I’m not sure if I have the 4 pin or 7 pin and what does that reference? The truck has had a brake controller spliced in and I want a Bluetooth unit.

Hello Spencer, thank for reaching out. The 4-pin or 7-pin references what kind of trailer plug is on the back of your truck. Since you say your truck already has a brake controller spliced in, I assume you already have the 7-way on the back of your truck since this is required on trailers with electric brakes.
If you do already have the 7-way, you can easily add a Bluetooth brake controller. For that I recommend the Curt Echo Wireless Brake Controller # C51180. This will plug directly into your 7-way and it will simply override the current hardwired controller. Then all of your brake control can be done wirelessly thru the Curt app.
