I think I understand now what you did. For each connector that you made, one end clips to the clip end of the 02 sensor and then the other end to the car. Is that correct?
If so I never thought of it that way as I always imagined the wires had to be cut and spliced in hence my confusion.

When I first did mine, I simply cut-n-spliced the wires on the o2 sensors to lengthen them. That was all fine-n-dandy until I had a sensor fail, and then the next sensor I put in was either bad out of the box (it was a Bosch, so unlikely) or i damaged it when extending the wires.

So I built the extension cables, the way pilot4fun did. (In fact I think I used his part numbers to order the connectors?!) Now I don't have to worry about suspect solder-joints creating impedance that throws-off the sensor. AND - I can simply replace the O2 sensor with a new one next time, rather than have to extend wires again.

It's worth it, in my opinion, to do the extension cables the first time.

Agreed. At first I couldn't wrap my head around it based on the picture he sent and then it just clicked. One of THOSE days I guess.
I like this idea much better as the sensors don't get butchered and can be swapped out easily.
