360 magnum O2 sensor install help

I found the wires. They were cut off about 6” after they split from the main harness. I don’t remember cutting them off, but I guess I did. Hopefully everything is there for me to connect to.

I do have another question. About a foot or so from the computer there are two wires taped together that come out of the harness. There is no plug on them, but in your picture I think it is the wires connected to the green plug. If I remember correctly one wire was blue and the other brown. What do they go to?

thanks.
The green connector is for the air conditioning (AC) low pressure cycling switch. It would be on the accumulator right by the PCM on your donor truck. Those wire colors match too. If you are not going to use AC just leave them taped back into the harness in case you want to add AC later.
