The wiring is that which is in the main harness (Brown wire) and in the ECU harness (Grey wire). This is a shielded run, with separate pin breakouts at each connector.

There was no real concern about maintaining the integrity of the shield, but would changing the length mess with the ECU's ability to properly perform the associated calculations for O2 sensor input?

This is out of my element, but I highly doubt it. The cheaper o2 sensors come with pigtails, and I've seen o2 extension used. From what I've read up (I'm doing doing work on my Subaru that involves moving the o2s), a good connection is what is required, i.e. soldering your splices rather than crimping.

Thank you again.
Splices are being soldered, as I found that crimp connections were killing my good hand.
