Open the trunk. Standing right in the middle of the rear of the car, it'* in the FAR right corner of the trunk, between the right rear strut tower and the rear seat, down low. BEHIND the carpet.
Looking for a pic.......Don't have one. Thought I did. Anyway, as I recall, it was a black 2-wire connector plugged into the selector valve (selects between inflator and struts). Looking at the plug straight on it'* shaped like a 'T'.
So if you pull your carpet back in the trunk behind your right rear passenger, you should see it easily if it'* there. Or at least see where the valve would be mounted.
