You can't read pressure from the oil pan. Easiest place I found is behind the engine by the starter.

There also is one by the head, but I find that one actually less convenient since it gets in the way of the coil. At the rear of the engine it doesn't get in the way of anything, and it really isn't that hard to get too...

Here is the location right by the starter, there also is the factory temp sensor just a few inches to the right in the photo below.
