I'm not 100% sure, however, I do have a 1981 Mark VI (nearly the same car) and mine is located in a housing mounted near the driver's side lift support in the trunk. It's completely hidden inside the housing, but if you follow the wires that are there, it'll lead you right to it. The actual button is on top, and to shut off the pump, you pull the button up, to reactivate the pump, push it in. If your car uses a mechanical fuel pump, though, it won't have an inertia switch. A mechanical pump is operated by the fuel pump eccentric mounted to the camshaft timing gear. You will be able to tell if it is a mechanical fuel pump by looking at the driver's side of the timing cover. If there is a plate with two bolts there, it's not mechanical. If there is a unit mounted to the timing cover with fuel line running to it, then it is mechanical. Hope this is helpful!
