As posted on my other thread, I'm troubleshooting the front O2 sensor. To make a long story short, I now have all wires hanging loose and need to figure out what goes where. The wire colors on the harness are:
Yellow
Green
Red/green
Red/something (hard to see)
Wires are very short, buried in the tranny tunnel, dirty, and in a dark place, so they're hard to see and I might've got some colors wrong.

The wires on the O2 ensor are:
Grey
Black
White
White

Can anyone tell me how to match them? I found this thread but the wire colors mentioned are different than mine.

Thanks in advance!

Bump! Still looking...

Anyone has a pic of the connection, maybe?

Thats a tough one, hope Axe, Dave or Gary will pop by soon, they should know!

Wish I could help more

have you tried Kia Tech Info

This is what I found for a '96
Hope this helps.

Thanks guys, both did help. The wiring still doesn't match my harness but now I know what each O2 sensor wire does. I'm one step closer.

I talked to a guy that used to work at a Kia dealership and he told me Kias are notorious for having wire colors vary from car to car. I'm going to try connecting the yellow/white as yellow and the green as blue and see what happens.
