have a look at pic#2
im a bit confused ok is that by the right side or left side of the engine? looks like the left right
so much for black and white drawings i can't seem to find the exact location lol thanks a lot for helping and dealing with me!
It's in the middle side to side, near the front of the engine. I didn't figure out how to open it yet. Scared to break the plastic.
