you can cut and solder the wire if you wish, but BEWARE, the O2 sensor cable is shielded. So if you want to retain the shielding to avoid any stray current that may alter the signal from the sensor, then you are going to have to spend time afterwards wrapping your joins. 2 wires carrying the signal are shielded, I used 2 core shielded wire and soldered my connections then heat shrink the joints like normal, then used aluminium foil tape where the splices in wire are to shield it again, copper works even better. Ran it back down over the shielding of the new cable and the plug end so there is a 1/2" overlap then heat shrink the lot again to keep it neat.
Just make sure you leave yourself enough cable at the plug end, you'll need a good 3 inches to solder everything neatly.
