Hello there , recently i swap my grey dash to a black one on my jdm civic eg6 and i dont know where this conector goes , also my radio doesn have power the fuse i okay . Is anyone knoe where this conector goes??

 

That is the connector for the sun sensor on a JDM EG6. It plugs in to the little sensor at the centre of the dashboard under the windscreen. It is only on vehicles that have the AUTO Climate Control, which only came in Japanese market vehicles. Your black dashboard may not have the hole for the sensor if it is not originally from a JDM vehicle. But, thankfully, you have the old grey dashboard still (right?) so you can see where it goes and make your own hole.
