It is located inside the upper intake manifold, attached to the rear of the fuel injector assembly. It is attached with a small clip. To access it you need to remove the upper intake. The only tricky part is removing the fuel lines. Be VERY careful when you disconnect the main fuel injection connection block as well as the injector nozzles themselves. This is what it looks like.
