Electrical assistance.

Hello, I'm in the process of trying to find the source of a power leak causing the reverse light to be on continuously.

On the picture below can anyone tell me if this is a standard connector, and if so does anyone have an idea where the two white wires connect to on the single connector at the bottom of it?

Think another 3 cable connector goes where the white is. (Remove white )
The white goes into a single connection

Unsure what colour codes though
