The least complicated way to do this is to remove the windshield wiper tub assembly. I know it sounds intimidating, but I've done it from underneath, by removing the upper manifold and by removing the tub. The tub is the easiest by far. Start by removing the wiper arms. Lift the plastic cap covering the nut and remove the nut. The arm is fitted onto a splined tapered stud so you may to use a battery terminal puller to get it to pop off. After that, except for torx head screw drivers, you won't need any special tools. Next remove the screws and speed nuts that hold in the plastic cowling, remove the washer supply tube and remove the whole cowling. Once that is off, you can get to the 14mm bolts that hold the tub to the firewall. Disconnect those bolts and lift off the brackets. Disconnect the electrical connector from the motor and lift the whole tub out of the way. That will open up the entire back end of the engine. You can see and reach all the wires and plugs. It is much easier than fighting it from the bottom. Plus, you won't scrape all the skin off your knuckles. To reinstall, just reverse the procedure. Only trick is to get the wiper arms back in the same position. But just keep readjusting 'till you get it right.
