O2 sensors. Swapping PCM Pins? Who has done this instead of buying the corvette o2s or o2 extensions? Any good writeups or info out there? I did a search and didnt find much. I should be wrapping up my LT install in the next day or so and this is the last piece of the puzzle.

This can be done but it is more work than getting the extensions or the longer wires. For a clean install, the harness should be removed and stripped before relocating the pins, also the unused O2 wires can be removed.
All the pins are on the C1 connector "blue"
Relocate the pins as follows
25 to 26
28 to 29
65 to 66
68 to 69
These are the low and high for both B1S1 and B2S1, ground and ignition are common.
