precat o2 sensor for cyl 4-6

Ok this needs to get replaced. I have the o2 sensor. Which one is it? Obviously one of the ones before the cats, but if i remember correctly the one for cyl's 4-6 is on driver side. Anyone confirm this?

thanks

There are 4 O2 sensors in total, 2 pre-cat, 2 after.

Both pre-cat O2 sensors are on the manifolds.
Cyl 1-3 is drivers side, cyl 4-6 is passenger side.

Yep nelson i know, but there are two right next to each other, and one is for cylinder's 1-3 and the other is for 4-6. Are cyl 4-6 the one's closest to the firewall? (further from the front of the car?)

Cylinder one is closets to the rad, cylinder 6 is at the firewall. So yes, you're right.
