NM DiD Coolant drain plug location

[Starman]

I did an oil / filter change last weekend and intended to do a coolant change. I have a sketch showing the coolant drain plug near the oil filter, but I could not find it.
Does anyone have a better sketch or even a photo of the plug location.
Is it forward or behind the oil filter, toward the driver or passenger side.
I ended up just draining the radiator (partial change) which took about 4 litres. I also changed the top radiator hose due to a small leak, and the inside of the alloy fitting that the hose goes on looked perfect, I tested the coolant with Castrol strips, and the old and new (both Mitsubishi) coolant came up identical.

Any help much appreciated

Right next to the oil filter - and if the dealer hasn't bothered to remove it lately - it might need a good poking to get it draining.
