Hello FLIP373,

You will need to remove the air inlet pipe and the engine cover. It is located behind the engine on the exhaust manifold between the engine and firewall.

I am adding a couple of pictures for you. You will need a mirror or an endoscope to see it. You could use your phone as well.

I will continue to look for a better picture for you.

Thank you,
Brendon
