On a 1996 Ford Falcon EL, the ignition coil is typically located
on the distributor. The Falcon EL uses a distributor system, unlike later models with coil-on-plug ignition. Therefore, you'll find the ignition coil as part of the distributor assembly, which is usually positioned on the engine's top, near the center.
To be certain, you might want to consult a repair manual specific to your 1996 Ford Falcon EL. A visual inspection with the engine bay open (and the engine OFF and cool) will also help you locate the distributor and the coil within it.
