The engine block heater cord on a 1995 Pontiac Grand Prix is located
in the driver's side of the engine compartment, near the bottom, usually tucked up against the block itself. It's often near the oil filter or the lower radiator hose. Because it's tucked away for protection, you might have to feel around a bit to find it. It's a fairly thick cord, typically black.
However, not all 1995 Pontiac Grand Prix models came with engine block heaters. This was an optional feature, dependent on the climate where the car was originally sold. If you can't find it after a thorough search, your car likely wasn't equipped with one.
