Hi all......I did do a search of the forum and did not come up with an answer to this question...if there is one and someone can link me that would be great....in the meantime here goes:

I have the standard old trailer plug on my car and the van has a 12 pin flat plug. The previous owner modified the flat plug adaptor of a 7 pin which operates all the lights fine. My question is, Is this legal to modify an adaptor that way? It looks perfectly fine...there is no way you could get a wrong connection or anything. I am just wondering if something went wrong would insurance still pay because of the modified plug? Is it worth just getting a 12 pin installed just to be sure?

Any feedback would be great!

Thanks!

C.

Been keeping well clear of this subject but something in back of my noggin start clanging.

WA so far only used 6 or 7 pin round small, any vehicle brought across ex fleet etc from Victoria has a large 7 pin round fitted.

If I am thinking correctly a 12 pin will be a flat rectangular shaped connector either two ros of 6 or one big single row of 12.

If the size of the pin/plug is too small of size how heck is sufficient amperage for especially electric brake supposed to work through a minimal sized wire ?

Use 4.5mmsq --8mmsq wire for brakes

When having 4x brakes [2 axles ] use the larger pins, for that matter if the space is free I use the larger pin for 1x axle of brakes as well .

So said the pin sizes it were too small? The small pins will safely handle 10 - 15 A. That is enough for a tri axle tyrailer. Most of us have single or twin axle vans so there is more than enough current carrying capacity in the small pins for our requirements.

A 12 Pin car socket is rectangular, with a row of 7 standard size pins on top, & 5 larger pins on the bottom. A standard flat 7 pin trailer plug will plug straight into the top row of a 12 pin car socket.
