Judging by the size and location, it looks like the one that goes to the Temp. Sensor located on the front of the air cleaner housing. I see that you have your air cleaner removed and I don't see the temp. sensor laying there like I do when my air cleaner is removed.

Ok, it is the live wire just above the FPR ....it is on the right side of picture. There are about 6 wires in that bunch that comes from the ECU:
1 . Water temp sensor - 2. Engine temp sensor 3. Air temp sensor 4. Air Flow Pot 5. One wire is grounded on top of the intake manifold #1 6. This is the live one which I don't know where it is supposed to go to. Thanks smk_texas |

Using the lenghth of the broken wire as circle radius should help to locate other part that is broken

Okay , Thanks for all the suggestions. I found out where this wire is supposed to go. It needs to be grounded to the engine block.

this grounding (W5 if I am correct) is used by ECU didn't you have any problems?

Yes. My check engine light is on. I got a code 4 which is Air Flow Sensor indicator. Is the CE light due to this faulty grounding ???? Please advise. Thanks
