In an effort to save money and also meet stricter emissions standards, Ford decided to make all of it's vehicles with returnless fuel systems starting in May of 1999. These new fuel systems allow for greater control of fuel, thus allowing Ford to get better gas milage and lower emissions. So, any car producted before 5/3/1999 has a return style fuel system while those produced on and after 5/3/1999 have a returnless fuel system. To determine your car's production date, look for a sticker on either your passenger's or driver's side door jam that has the vehicle production date.

Cycle the ignition from OFF to RUN 4 times within six seconds, then turn it back to OFF. The alarm light will stay on to confirm programming mode. Press any button on the first transmitter. Alarm light will flash to confirm transmitter programmed. Press any button on second transmitter. (Up to four transmitter total possible) Turn ignition to ON. Alarm light will turn off to confirm end of programming mode. If you car didn't come with remote keyless entry, then I don't know if this will work. If it did, but you just didn't get a transmitter, then it should work.

The ground wire can be mounted to anything metal. You can screw it right into the trunk if you want. Just be sure to check under the car first so you don't screw into the gas tank or anything else important.

Look right above and to the left of the brake pedal. There's a rubber grommet that you can push out and you can run the power wire through that hole.
