Ignition Module Compatability

Hi All,

I notice that motorcraft still offers an ignition module, but that it's not crosslisted for a 4 cylinder.  Certain aftermarket items are crosslisted.  In my mind I am thinking "this thing has to work" but has anybody tried that?  

For instance, the one carried by the Mustang resto vendors is Ford's part number is  DU2Z12A297A and they generally show it fitting everything under the sun up to 1987 including thunderbirds.  Cylinder count clearly has no impact on this.  I ordered one for my Mark VII but I am thinking I might try it in the TC just to see how it does.  I doubt I would learn anything from that.

They also still have  5U2Z12A297B which fits a lot of cars through 1990 and trucks to 1997.  Cylinder count clearly has no impact on this.

They also show 5U2Z12A297D which covers the mid-90s cars up until they quit using distributors, I guess.

Just making conversation mostly.

I do know that TFI modules came in at least two versions. One version had what Ford called CCD which stood for Computer Controlled Dwell and the other version had fixed dwell time. Not sure in the two versions are interchangeable or not. My guess is not.

Well, I might do some experimenting, but I don't have a scope.
