Relatively easy. Under cowling on passenger side (providing you're in US), per post by Stewart. One thing, some instructions I've seen say you have remove tha windshield wiper arm. That is not so on US models. Only the torx screws (I think 3 or 4) to gain good access. Do not need to remove entire cowl, just enough to lift up cowl to gain access. Make sure to put it in the same way it came out (not upside down).
