Nato socket to 7 pin converter? is there such a thing

Hello

Thinking in my head about converting the nato lights on a trailer I was going to un do the Nato plug and wire into a junction box and then attach a 7 pin plug to the other end so it could always be converted back?

this idea (taken from another build on this forum

However an easy plug and play fix would be something like below? but is there such a thing? from a Nato plug to a 7 pin plug? (I have not found one as they are all 13 pin to 7 )

Then all I would need to do is change the bulbs?

Thanks

You'll nly need to change the bulbs if the trailer is 24Volt.

There is no COTS adaptor available to or from the NATO 12-pin set up, because the people who use NATO sockets don't use civilian equipment.

You could obtain the NATO socket from the back of a military vehicle and wire it onto one end of a lead with a seven pin 12N plug (or 13 pin, whatever you need) on the other, but it is going to be far less convenient that simpy fitting a normal lead to the trailer. Realistically, when are you going to want to use a NATO 12-pin connector on your trailer? Unless you own an ex-military LR, it is functionally useless!

My advice is to remove the complete 12-pin plug and lead, replace it with a 7-pin plug and lead, and keep the NATO lead you have removed in case one day you do want to restore the trailer to as-built condition.

Good call to be honest and your right,

I'm unlikely ever to need the 24V Nato plug. So just store it.

Is it a straight forward job to wire in the 7 pin socket as I would like the front lights and rear fog to actually work,

Thanks

Yes, Pin 2 as noted in my post above.

The 12N pin allocations are as follows, with the colours used in 7-core trailer wire:

1 - Indicator Left (Yellow)
2 - Rear fog light (Blue)
3 - Earth (White)
4 - Indicator Right (Green)
5 - Offside side, marker & number plate light (Brown)
6 - Brake lights (Red
7 - Nearside side, marker & number plate light (Black)
