This is going to sound like a dumb question, but I can't see a plug to plug my IACV into. I bought a 03 discovery with a bad engine. When I bought the disco, all of the intakes were already removed, so I did not take it apart. I bought a used engine and have installed it. I did not see a plug for the IACV coming out of the wiring harness. I believe I have everything else hooked up correctly. The car starts and runs but is having a hard time idling (wouldn't idle but I tightened up the throttle cable so i could keep it running). I do have one more item that needs plugged in. On the passenger side wheel well, closer too the firewall than the fuse box, there is a little 2 prong plug that needs to be plugged in. Is there a wire that goes between that and the IACV??. When I bought the car, the many of pieces were already in boxes. Pretty much like a puzzle. I need to look at another disco to see where the IACV should be plugged into. Any pictures or help would be appreciated.

 

Some two prong plugs are for ABS sensors....

Here is pix of C0641, the IACV connector. The RAVE is the shop manuals set, it has circuits manuals that show the wiring diagrams, and each wire has small numbers on the drawing that index to a connector and pin. The electrical library has pictures of the connectors and locations.

 

Thanks for the information. That is exactly what I am looking for. So does C0641 come out of the wiring harness?. I have looked and looked and don't see another connector from the wiring harness. The ABS sensor makes sense too. I bet I have a wire down in the wheel well that needs to be plugged into that one.

 

Part of the harness. Keep looking.

 

Thanks for the help. I will look when I get home. It is so tight between firewall and engine. I might have to remove the motor mounts an lower the engine to get a better look.
