Did your truck come stock from the factory with this connector? I have never seen this before, it was always added afterwards. I actually have a pigtail I made up to go from the 7-pin round, to the 7-pin flat, from when I used to do commercial construction, so i could tow my trailer with my work truck. Haven't needed it for 20 years now though.

Jim I can not say with certainty when Scamp switched their wiring harness set up to the more traditional RV standard you are familiar with. Its simply my guess that it was within the last 5 years for a couple of reasons. A few people have recently mentioned here that Scamp no longer uses the centre pin for the blue brake line - as I recall those who have mentioned it appear to have 2010 or newer trailers. Secondly the PDF wiring harness diagram I posted is the same as the one in the original 1992 manual that came with my Scamp as well as the online manual they had on their web site up until a few years ago. Scamp switched a few years ago to the new video interactive manual on line and the wiring diagram is now different. Floyd is great at knowing all things Scamp, so he probable knows better than I when the wiring change was actually made.
As far as my trucks set up goes - it did come from the factory with the full tow package and wiring per the detailed option sheet included with it and all the parts & install are factory - nice and neat.
BUT the truck was 2 years old when I got it so it is possible the previous owner had the wiring switched around for his own set up although I would be surprised if he changed it as all he pulled was a small boat and used a 4 pin adapter for that, which they included with the truck. So what if anything was actually changed on the truck side after it left the factory I can not say with certainty. Just happy it was all neat and tidy and plug and play with my Scamp, including the brake controller.
I do know though that when I took the Subaru in to have the seven pin harness added to the factory 4 pin and a brake & charge lines run for the Scamp I showed the installer the Scamps wiring harness diagram and the party doing the set up took one quick glance at it and said ok and handed it back to me - never looked at it again while doing the wiring. When I got the car home and plugged in the trailer, it all worked as it should. So I am assuming it was something the installer had seen many times before.
