It was my understanding that very old Hondas (pre-OBDII) had the 3-pin connector.
Honda HIM comes with a 3-pin adapter for those cars.
But I also found the same connector dangling under the dash of my Pilot. What is it used for?
I have a 2015 pilot Exl 4wd. We would like to set it up to tow our aliner camper. Is our model pilot prewired to accept a 7 pin trailer wiring harness or just a 4 pin. Also will it have a pig tail to plug in a brake controller under the dash. I got conflicting answers from our local Honda parts...
