Engine bay ignition wiring with green arrows labeling TFI-IV Mod…

DIstributor-mounted TFI-IV ICM module & SPOUT connector on '84-91 trucks. This is a V8, looking straight across the radiator & fan belt at the base of the distributor.

Distributor-mounted TFIs were the subject of a class-action lawsuit against Ford due to their high failure rate. In '92, Ford moved the module to its own heat sink on the L inner fender, and modifying an older truck to this configuration is relatively cheap & easy.



Distributor Clampdown 24-33 Nm; 17-25 lb-ft
