I haven’t been able to get to my plane and I might be imagining this, but I think the rear one is on the firewall visible from the oil door. I theorized so that one can open the cowl flaps with a deactivated motor in a pinch because you really need those cowl flaps open to get the rear cowling off. Manipulation of the quick connector would reaching through the oil door (with skinny hands and arms!). I don’t have a front placard that I remember but expect it would be somewhere near the mechanism but wouldn’t have to be visible from oil door in that case. Just somewhere on firewall that makes sense.

I guess an important point here is that there is a process, especially for the rear, to get cowl flaps open if motor isn’t working for further dissassbly.
