Ok...Who knows what wire color is for what sensor? I just bought the Bosh O2 sensor and don't know which wire goes to what? The colors on the instructions from the Bosh sensor is not on my 95 Si. I know there are four wires from the Bosh 3 white and 1 black were do they go?

 

I just got one too. Mine has two white, one gray and one black. Mine is the O.E. style, meaning the "factory correct" styled plug is already hooked up to the wires. It was just a simple plug in. Is yours universal or something?

 

Not sure!...I went to advanced auto and that's what they gave me (part# 15733). What colors are on your engine harness (o2 sensor)? My engine harness was converted from Rywire so the colors are orange,white,yellow,purple(o2)....is that what your stock harness's colors are?

 

ANYONE?

 

O.K., mine are yellow w/white stripe, orange w/black stripe, green w/black stripe, and white w/red stripe.
Hope this helps you.

 

Well took it back to the store because they said they gave me the wrong part. The correct one is coming in tomorrow.
