It's on the engine harness that goes to the injectors. Black wire with red stripes. A single wire. Mine appears unconnected. It looks like mine has a spade in it, possibly from a sensor?

Where does it plug in? There is another connector that goes to the temp sender at the very back of the engine. This is not that one.

Is this sensor for the temp gauge?

Might be for the A/C. It was a single wire connection.

My rule of thumb (prior to labling things that don't plug in any more) is see how far it reaches) and what plugs are in the area.

That's underneath the intake manifold, the wire doesn't look very long, and it has a bigger plug than the AC which is pretty small. Looks like the oil pressure sender to me. Off the top of my head I think the starter has a screw on ring post and a spade terminal also. (I have too many parts still on my car to check the colors or I'd go look.)

Wait, isn't that the clip for the O2 Sensor? That's about the right area for it.

Black wire with red strip? That's the positive lead for the battery. [duck]

Juan:
From memory the wires in that area are for:
The O2 sensor, the coil pack, the temp sensor on the back of the block, the starter relay, the oil pressure sender and the injectors. I don't recall any AC connectors back there. A picture might help.

According to the wiring diagram it could be the blower motor relay from the starter or the cooling fan relay, the refrigerant pressure switch to the a/c clutch, or the ignition switch starter interlock. Can't find anything else that has a blk/red wire.

O2 sensor is different color.

That is the wire for the water temp gauge sender. The terminal looks like it broke off from the sensor and stayed attached to the connector. In you pix, you can see the rubber plug that sticks out of the head, the sensor is near that plug.

Remeber, you have 3 water temp sensors.

For ECU is on the back of the head and is green square for 1.6 and gray oblong for 1.8

For fan on 1.6 at thermostat housing

For temp gauge, back of head, passenger side for 1.6, drivers side for 1.8

It plugs in the back of the head. Its the temp sending wire. There is a small male conector under what looks like a T Stat on the back of the head. Its kinda low and plugs in from the passanger side. Never trust Mazda wiring diag. they are offten wrong.

Al and others got it right. Temp sender on the right back of the head. Not the ECU one that is under the coil pack. Thanks everyone!
