hey guys need help identifying some wires on my 99 obd2b auto engine harness.

Hey man, I have a wiring question for you.

Im doing an auto to manual swap lsvtec in my 99 civic obd2b car.

The engine harness was already in the car and Im wondering what these wires go to that were cut off? There are 3 wires coming out of the hard plastic piece that goes under the intake manifold on all the harnesses. If you could help me it'd be greatly appreciated.

After I do the iacv 3 to 2 wire fix and use a obd1 jumper harness any other sensors I wouldnt need other than the extras for the auto tranny?

Thanks a lot

 

Anyone?

 

Label/number each connector of interest to you in the pictures and also list the number and color of wires in each connector. Help people help you.

 

I see a bunch of wires........which one do you need to identify, what car was the engine harness pulled out of?

Going by the image, it looks like it could either be the alternator plug missing or the cfk plug missing.

Color codes:

Brown/Black = probably goes to the junction box near the ecu plugs
Blue/Orange = STS
White/Red = CKF M

 

Either tell us the three wire colors or post better pictures. For example, for two of the wires, I can't tell whether they are Orn/Blk or Blk/Orn, or Wht/Red or Red/Wht. I think the third wire is Blu/Red. Is this correct?

 

I think you nailed it Tony.

The CKF sensor has three wires: Blu/Red, Wht/Red, and Brn/Blk.

OP - I don't think those wires are needed for the swap so just cap them off.
