Hey i ahve a 92 civic dx hatch with a 95 d15b vtec. there is 2 sensers rite behind the distributer cap and there not hooked up to anything y is this?? the car seem to run fine and also theres a vacume hose behind the fuel rail that looks it could conect to a hole in the intake manifold but nothin to lip it on to. could anyboday help tell me what these are all for and what ecu should be in the car? sorry im new at this.

 

the 2 wires behind the disributor is for your Vtec i belive one is green and the other is gray. this means your Vtec is not hooked up right now.
How big is that hose??

There should be a P28 computer in the car, this is a vtec computer. its located on the passangers side, in the car, located next to your leg at if your sitting in that seat. pull the carpet off and check for the computer code it should say p28.
Hope this helps some.
