I don't know, the 9991 Grand Marquis has not been built yet, but

if I know FORD, they will put it somewhere where it will be tough

to access similar to the thermostat or the 2nd spark plug from the

rear passenger side. Autozone has a do it yourself feature on the

internet that has a lot of instructions for that kind of stuff;

they will want you to register first.
