    I'm looking for any and all hi-resolution photos of early* U.S.-delivery GT or GTB/4 complete smog pump assemblies and related wiring connections, former preferably mounted on the engine and in the car.
    Reference to VIN would be even more helpful.
    PM or email options also available if privacy is preferred.
    Thank you in advance.

    *Up to VIN 14500 or so.

    Narrowing the research to wiring harness, i.e. any photos (& VIN reference, if available) of smog pump wiring lead connectors (as built or found) in U.S.-delivery 365GT 2+2 or "early" 365GTB/4 would be helpful.
    Thanks in advance.

    I'm guessing this is for concours purposes?

    I removed the air pump from my 365GT long ago, and when I decided to enter it in a regional FCA concours, I couldn't find it. So I figured that would cost me a point, or fraction of a point, or whatever. The judges apparently didn't notice (so no points off), but docked me for some other stuff which was not actually wrong-- no point in arguing, but I checked later and sure enough, I was right.

    So I probably wouldn't get too worked up about it. Maybe at a national meet they would be more likely to notice?

    Gentlemen, thank you for your replies.

    Basically, this is just a (small) part of my years long and on-going research on variety of (obscure?) details and changes made during Daytonas 4+ year production timeline.

    This case, for example, stems from having myself seen (& photo documented) several different electro-magnetic clutch assemblies & wiring set-ups on them and that the September 1972 365GTB/4 parts manual indicates TWO separate updates on these clutches sometime between mid-‘71 & mid-‘72.

    It appears some early(?) 365GTB/4 “smog” pump clutches were same as those used in 365GT 2+2s and that’s why I’m interested in details of latter also.
