Ok, it'* not what you think. Once a friend told me he liked to ....
I am drilling out the rivets that hold the heat shield covering the O2 sensor. What a pain in the ***.
I guess this O2 sensor is not meant to be changed very often. The connector that connects from the O2 sensor to the wiring harness is midway down this heat shield.
The O2 fooler plugs into the harness connection.
I'll just rivet the cover back on again cause I'll never be changing that O2 sensor again.
.....now, if I can just get those blasted plug wires off those plugs.
