OK,

So I am putting together an egine for the first time. I took it apart so long ago that my paint markings kind of wore off. I have it mostly back together with the help of the mazda manuals and all-data, but there are a few connectors that have no mates.



The way I routed the harness left me with 2 plugs under the manifold with nothing to plug into. One was green so I figure its a diagnostic and can leave it, and the other was some weird round 1 pin connector type dealie.



If someone could post picture of what a t2 engine looks like with the UIM off, I'd appreciate it a lot.

the green one is the coolant temp sensor. is it shape like the injector connectors? and the other could be for a few things but it might be the temp gauge sender idk best of luck

green one goes in the back of the waterpump



single pin might be 02 sensor?

I immediately thought o2 sensor too, but I think it's in the wrong place from where it used to be.
