I found plugs in the harness that arent going anywhere, i wana know where they connect to.
Also my car is running really rich and boggy maybe because the plugs arent connected?
Thanks.


theres four in this pic. two have blue inside. the other two are rectangle-ish with yellow inside.



also found this big one with white inside behind the intake manifold.

 

year/make/model of car? what engine? closer pics of sensors?

 

Its a 97 Honda civic hatch with gsr motor. havent found anything that they connect to.

 

Ok the two blues are intake air temperature sensor (the one on the GSR is on the intake manifold itself and is a round sensor not square). The other blue is evap purge and the GSR is round not square so you'll need to swap plug on both those sensor to get them to work. I can't tell from the pic what the two yellow plugs are can you take a closer pic? The bottom sensor is the CKF sensor that goes near the crank pulley. If your engine is OBD1 it won't have it, if your engine is OBD2 it will have a 2 plug connector and you'll have to swap plugs, match the two matching colors and disconnect the third brown wire).

 

BTW what ECU are you using? Any check engine lights?

 

So i have to switch the blue plugs to the gsr circle ones. the intake air temp. goes on the manifold, and where does the evap purge go? since their square does it mean i have the original civic harness?
I have a p73 ecu and the check engine is on.

one yellow plug has three pins in it, the other has two. their wires go down by the oil filter.
