You're going to have to extend the wire somehow. Cutting and splicing is never a good option, but it is what it is. If it were my bike, I'd source a new pair of the connectors that go on the cable and build a new patch cable. Plug the sensor into the new patch cable, then the patch cable into the bike harness. As a second option, I'd de-pin the connector, add a couple of extension wires to it (a single splice point as opposed to 2), re-pin the other end and put it in the new connector.
