What is there to screw-up?

The existing hole is 1/4" which is perfect for tapping 1/16-27 npt. Just tap away. Then get a 1/16npt x -4AN adapter, some pipe sealer and you are set.

It appears you tapped the head or found an adequate fitting... ?

Great find. I could see putting the rest together based off of those.

heads are tapped, 1/4 pipe thread to -4an and then you just run it how you see fit

That is what I did on mine, works great, only cost is the AN adapters..
