tried this in eg+ and got no where...so here we go. what harness does your (Si owners with b16a2) secondary o2 tie into? is it the main engine harness or is it something in the cabin? pics would be HUGE if you have some. thanks a lot for anyone who can help me out.

heres the other post if you want to see what was suggested already...

thanks in advance for any ideas (or facts) that anyone can give.

 

It ties into a harness inside the car under the dash....but it goes to the ecu. I found that out when i was swaping wiring. I have no pics cuz digi cam is not cooperating...But yes, it is inside...under dash, not in engine harness. Plug in is by the srs unit. good luck.

 

thanks you VERY much..i will search around the srs. does that mean there is some type of extension for the actual o2 harness? because right off the sensor its only about 5 - 6 inches long.

 

up for more comments...

 

i belive there is an extention piece of harness that goes from the o2 to the harness, but i'm not 100% sure on that.

 

up for more comments...is there any truth to the extension harness idea?
