What prevents the ignition coils on the F250 from being used with the V-8 engines?

The ignition coils on the F250 and the V-8 engines have different connectors, specifically, the use of a 4-pin connector in the V-8 engines is a critical factor that prevents the interchangeability of the ignition coils. This difference in the connector design means that the electrical connections required for the ignition system are incompatible between the two engine types.

If an ignition coil from the F250 were to be used on a V-8 engine, the mismatch in the connector would hinder the proper connection necessary for the ignition system to function effectively. Therefore, even if the coils were otherwise similar in function or performance, the distinctive electrical interface created by the 4-pin connectors ensures that they cannot be used interchangeably.

The other options, while related to potential differences between various engine types, do not specifically address the connector compatibility issue that is the primary reason for the incompatibility of the ignition coils.
