Custom Wiring Connector, 7-Way RV Blade, Select Nissan and Suzuki #56226

I like Curt products. Durable, well made, and with great instructions, I give 5/5 for most everything I've used. For the most part I find what I need, but this situation, as it pertains to a 2010 Nissan Pathfinder is a little tricky and you might want to know about it.

Not all 2010 Nissan's have the same towing package and OEM wiring or so it seems. Now I haven't been able to get any mechanic friends who have this level of Nissan service history detail to collab, but my bought used Pathfinder has the Towing packing with the 4 pin flat connector. I'm to be honest, not sure if this was bought aftermarket or not, but I was told it was supposedly sold new with a/the towing package. It however does not have the 6 pin waterproof connector as this kit has. It has an identical 8 pin connector instead that carries 5 signals (connection C51 to C125) for an installed official Nissan 7 pin or 4 signals for the flat 4 pin (connection C50 to C124) which is illustrated on the official service manual. I believe the difference is because of which sub harness is installed coming from connector E41 to C1 located in the rear drivers side of the vehicle. This information is from the service manual for a 2010 Pathfinder as well as looking at the vehicle.

TLDR; I know. My point is before you buy this part, do yourself a solid, and crawl under the driver's side rear of your 2010ish Path/front/mada and confirm you do have the gray 6-pin waterproof connector and not the gray 8 pin.

Also, Curt people, can we please specify what you mean by OEM in detail for the context of this part so others won't buy this part and only to be confused?

Thanks.
