That's an auxillary power supply for an led light or gimbal. Be careful not to let the two ends come in contact, they're hot and will short out. I found that out the hard way, DJI should really just put a balance connector on the ends instead of leaving them bare.

I agree with Woody, if that's what yours looks like.
If you stuffed them up in the hole, they may find a way to short.

The OP said they were not powered though. Maybe I misunderstood him.

So then that wire I can use to power a vtx? I'm assuming red is hot and grey is negative right?

Made in China capodrone81, but yea, it should be that way.
Voltmeter cheap, repairs expensive.
