We just recently had a rear bar fitted. At my request they did not refit the trailer wiring socket. Years ago I seemed to always need an adaptor when hiring or borrowing trailers. So I though that I would fit it myself at a later date as we do not normally tow anything. We do not own a trailer or caravan anymore. Simple!! NOT
I started looking at the Narve sockets and run into a seven pin socket with a “reed switch”. I know what a reed switch is and now realise that it is to compensate for a “no led connected” situation when the trailer (with led lights) is not connected. I then find a comment on LCOOL.ORG; “Re-wired the trailer coupling with 12 pin (for Ultimate Camper Trailer”. Simple choice be blowed.
The only things that we may dtow is a hired trailer for a cleanup rubbish tip run or a rented etc T-van, Conquerer or similar for a long remote trip.
The more I search the more I get confused.
From you learned people what’s the best to fit? Just a standard 7 pin flat socket without any reed switches or what?

G'day Phil
A 7 pin flat plug is probably the most common and reliable as they don't seem to fall out as often as the round 7's do.
The reed switch is not for LED lights at all, it is to switch off the reverse camera eath if and when you open the lid to insert the plug.
The little MAGGOT in the lid allows the reed to open and therefore turns off the camera earth cos why do you want to see the trailer all the time.
The Magnet closes the reed when the lid is closed and makes it so you can use the camera.
All that is for normal people though and I would switch a camera manually anyway.
You can confuse things and add a 12 pin and use more pins for the same purpose or switch more things on and off in the trailer if you so desire.
If a reed is used anywhere it is only rated to a few milliamps and not for lights, even a few LED arrays will fry a reed quite swiftly and they are only mercury wetted contacts. As you know reeds burn
well.
PS Some people would use a 24pin connector if they could get one, after all more is better isn't it.
You can use pin 2 for reverse signal or with the plug wired correctly you can use 2 as a feed for a reverse camera on a trailer, switched from the front of course.
Not sure who tries to use REEDS and LEDS, perhaps they don't they just think it is done.

I used heaps of reed switches on the train layout to ground the
grid on a flip flop circuit to start a sequence of events to change power, points and lights and then to stop any other train from entering the occupied section. I know them
well. Very handy little gizmos.
Back to the point at hand.
So I think we shall just go and install a new flat pin without the reed switches. As you say most will come up with adaptors. If not then if it's that important then we could just purchase one.
Maybe I should put a 24 pin one on for all the bling. A row of leds up and over the front of a van and don't forget a few rows of blue underneath. NOT.
Thanks

On my vehicle the reed switch switches off the reversing sensor so you go not get the beeping noise because you are close to the trailer.
It may also switch off the revering camera, but what does it matter, the camera is only on when reverse is selected.
