Make sure you have the right connector hooked to the front or you'll have no fuel control.

The one in the upstream one at the manifold is already plugged into the main harness, but I'll double check, thanks

Double checked, and the plug in my photo is definitely for the downstream sensor. The upstream sensor in the manifold is plugged into the correct harness connector for it. The catalytic converter is long gone, and I do not plan on putting one back on it due to cost. I found a pipe online , that has a sensor bung on it, and I found a spare sensor in the parts that came with the car, it'* heated,(same as my upstream) no clue if the spare one is up or downstream. My question is, do I need to have a downstream, since the converter is gone? Or can I go with that pipe, and use that spare sensor I have? Main purpose for the car is mostly in town driving, delivering newspapers with it.

The downstream is to monitor the health of the cat. No cat then no need to monitor. That will not turn off the CEL. Do you have inspections?

Ok thanks. No inspections where I am.
