I'm sorry. Just answer will not allow outside contact. Doing so will get me banned from the site. Are you hooking up and air / fuel meter? If so, what brand?
Customer: replied 7 years ago.
im hookin up a chip. it needs to be connected to the signal wire on the 02 sensor that is located after the cat. there are only 2 o2 sensors on the 2009 civic lxs right?
Expert:  thebesthonda replied 7 years ago.

Yes, correct. No problem. I thought you were hooking up an air/fuel meter. These need to be connected within 6 inches of the e.cu. and the wire color changes to red/white within the harness before it gets to the e.c.u. That was the reason for my first info. request.

 

The colors on the o2 sensors vary. Tell me all 4 colors your o2 sensor has and I can look up the signal wire.
