I put a JDM GSR into my 95 Civic dx and using a 92-95 civic ex harness. Can any one with this harness show me a pic to which plug is for the IACV and which is for the IAT sensor? I looked everywhere and find nothing helpful unless its a picture. I heard you can burn your ECU if you get the two mixed. Also got a question about the heater inlet and outlet hoses. Which one is the in and which is the out on the firewall? Thanks in advance!

 

your iacv is on the back of the intake manifold the one that has the water hoses the plug a a round one with green and black wires on them and the other plug should go on the manifold right next to the fuel rail hope this helps

 

you got to be more specific, there are two plugs that fit both the iacv and the iat sensors. You're just explaining about the water temp plug. I need to know exactly the colors to the iacv and the iat plugs for the ex harness.

 

The Blu/Yel & Yel/Blk plug is the IACV, and the Red/Yel & Grn/Wht plug is the IAT.

For the heater hoses, looking at the firewall, the left one is the Inlet and the right one is the Outlet.
