I'm assemblying my car, then I found out these thing is disconnected.

Does anyone have any idea?

Did I connect things wrong?

 

Looks like the knock sensor to me.

 

oil pressure sending unit

oil temp

and a coolant line

 

damn, I was way off.

 

Knock sensor is on the front rotor housing

 

So, how do I connect oil sending unit?

or oil temp?

 

The sensor that is unplugged is the sensor for your coolant temperature gauge. If you have another gauge, then that isn't too important. If you don't have another gauge, then hook that wire up, and go buy a water temp gauge, the stock one sucks!

 

there should be a little connector hanging around that area somewhere, look all over for it, or a bare wire.

 

Could you anyone gimme a more specific answer for this?

 

P'Cola is right, the sensor that is unplugged is for your stock coolant temp gauge. Just look around for the plug, it should be there somewhere.

 

So.., that means one line should be directly coming from temp gauge??????

I don't know..

 

P'Cola's correct. Coolant temp sensor is unplugged. The large unit to the right is the oil pressure sensor and the bottom water line goes to your heater core.
