Hi All, Im a newby to the MDX world. I recently bought a 2014 Acura MDX w/o an OEM trailer hitch/wiring. I installed a Curt (aftermarket) tow hitch and am now looking to add a brake controller/wiring to pull a pop-up camper. Anyone have experience/recommendations on how to go about adding a 7-pole connector? I have found a 4-pole wire flat, but due to needing the brake controller, I require a 7-pole connector. Im not certain if there is a simple solution to what I am looking for. Also have found I may need a relay? Any assistance/guidance is greatly appreciated.
