Hey Stephen, yes you would need a brake controller installed in order for the Curt 7-way tester part # C73NR to be able to test the brake output circuit. There won't be voltage on that circuit until one is installed and activated.

Thanks, Jameson.... that makes sense! Just purchased a new Frontier a week ago and my concern/reason for testing was that Frontier pickups had some issues with brake wiring in the past. Installed my Prodigy P2 today on my new Frontier ... everything works as it should. Thanks for your reply. Steve

@Stephen Yeah there's a reason people STILL call the P2 the best brake controller. It works really well and is super reliable.

Hey John, what you need is the part #ETBC7 as this comes with everything needed to adapt your 4-way to a 7-way plus wire up a brake controller like the P2 #90885 and activate the 12 volt charge circuit for the battery.
