Hey guys im putting my engine back together and i came across this plug where I don't know where it connects to. The wire is taped with the fuel injectors to the irons and the Thermostat housing wires. Thanks in advance!

 

I'm pretty sure that on my car there are two wires that plug into the back of the water pump. Those both look like the two that go there. You should be posting this in the 2nd gen forums, though, not drifting...

 

S4? S5? green is for coolant temperature sensor. im guessing this is for a s5 as im unsure of the black one

 

i was told by other members of club that the black one is for electric fan
as stated above green is coolant temp goes to back side of thermostat housing

 

Electric fan for the radiator?

 

Looks like an o2 plug to me..
