Yep, lift the tank. From above, look in the right side recess between the frame and the front of the airbox just a few inches to the right of the ignition switch (but below it). FYI it is tied down so it is difficult to connect anything to it as it has very little free play (i.e. you can't grab it and pull it a few inches toward you to make it easier to connect). If you want, you can search for my thread on installing the EasternBeaver 4CS kit. I reference a video I made where I talk about connecting to it. You'll also need to check if your heated grips have the right kind of male connector.
