Where is the tfi module on a 1985 Lincoln town car?

There's no single "TFI module" in a 1985 Lincoln Town Car in the same way there is in some later Ford vehicles. The 1985 Town Car used a Distributor Ignition system, not the Throttle Position Sensor (TPS) based TFI (Thick Film Ignition) system that came later.

The ignition system components are distributed:

* Distributor: This is the main component, containing the ignition coil and the electronic ignition module (often referred to as the "igniter" or "control module"). This is located on the engine, typically near the front, driven by the camshaft.

* Coil: Often integrated into the distributor itself.

It's crucial to consult a wiring diagram or a repair manual specific to a 1985 Lincoln Town Car's engine (likely a 5.0L V8) to pinpoint the exact location of the distributor and any associated control modules. The location of the distributor will be readily apparent upon visual inspection of the engine compartment.
