@jesmed1: Yes, that is the part! There appear to be 5 orifices to disconnect and connect, but I cannot find where the 5th one is; The Mazda repair Manual my friend found does not have a clear diagram of the 5th underneath.
Wish there were a three dimensional diagram in a manual that one could maneuver around to look at all sides of a particular part in its place in the car, up, underside, each side, etc. (maybe I will check You Tube…)
@the same mountainbike: My normal pattern is to think I cannot do something, but if I tinker with it, and stare at it, go away for a while, come back a few times, I generally can do this. But, your advice is well taken.
Both of you did address the safety concerns I had which was the primary stumbling block, thankyou! Now, about that 5 orifice…
