Question about O2 sensor pigtail wiring

[Rak123]

Hey guys, so the clip for my oxygen sensor caught fire on the manifold at my last drift event.
I got a new oxygen sensor and a new pigtail today, so I went to go solder the pigtail in.
But I have a question, there are 2 gold wires and one silver wire for the factory harness, which goes where on my new pigtail?

You can see the 2 gold wires on the left and the silver one on the right, also one of the gold wires is thicker than the other one

And this is the new pigtail, there is a black, white, and brown wire for it.

So if anyone can guide me as to which wires go where I would appreciate it.

The engine is an sr20 notchtop
