What is this on the right side of the engine block?
This is on the right side of the block right behind the right engine mount. It looks like a brass bolt with a wire terminal. Am I missing something or is it for an option that I don't have? The photo is taken from the right wheel well and the engine mount is just to the right. 2017 SR5

The 2010 service manual shows two engine block drains. The one on the left side is very difficult to see and access. I have drained coolant from both sides of the engine block on a 2011 Trail by referring to item 4 in the following image which points at two locations. The 2016-2019 service manual shows only one engine block drain on the right side.
