That is the correct spot. It is fairly high up and as I said I removed mine, drilled and then replaced it, but its hard to get out with 4 clips on it and mine popped out (I was working alone) and fell into the cover under the engine that I had to fish out). If you shine a light from the inside you should be able to find it looking in the engine compartment (preferably a dark environment) to see if there is anything in front of it. There wasn't on mine, but you should drill slow just to be sure. You need to have 3 hands to do this it seems.
