I think, only the piece that is connected with the fog light should be replaced, and of course you have to buy the fog light as a separate component.
because the US spec piece does not has a place to mount the fog light, thats why you have to buy the required peice, you can buy it in middle east, or in UK or in japan market, because in these locations they sell gtrs with fog lights.
It is highly appreciated if someone corrects me from being wrong.
I am planning to make a new thread ,,, which is about how to convert a US spec GTR COMPLETELY into a JAPANESE or UK spec GTR. which means making the US gtr has the following points:-
1- The front LEDS is turned ON while the headlights are ON (at night) ( I think this problem is solved by the amazing alexdavis
, thanks alexd your AWSOME) although this problem is solved, but the solution should also be included in the thread that I am planning to create.
2- Rear Fog LED that can be turned ON and OFF whenever the driver decides (SWITCH) + this fog light should be connected to the brake's light, and turned ON while you hit the brakes and OFF when you remove your foot from the brakes.
The two options above, can be implemented if we know exactly how the UK,JP specs oprerate.
we need a help from UK, middle-east and Japabese guys who own a 2012 GTR. we need them to explain to us how the fog LED/ front LED operate and where are the controls in the interior
