4x4Pinz,
That connector sold by SAV is the same as used by Range Rover, only prewired for the typical flat 4 trailer connector( though more money). A fast plug and go for the less electrical inclined.
And as far the wiring connectors BS. I have 9 vehicles of different eras and makes with 4 different sockets and 6 trailers with 3 different connectors. These adapters make it easy to move the different trailers with any of my vehicles, at any time. The magnetic lamps are fine for most trailers,but they don't stick to aluminum and trailers without a flat surface.
I have been on several MV boards and solve trailering problems for different vehicles and trailers in a permanent fashion without devaluing either, yours is only good for a Swiss Pinz. Many here tow their trailers with more than just a Pinz.
