Have you a breakers yard nearby?
Other than an insurance claim, trebor has the answer.
Smaller breakers especially have cars lying about half broken, and they may be able to help you with the loom part which connects to the sensors, and possibly the rest of the bits you need. It's just a matter of spending a few hours ringing around to find a Jazz that hasn't been fully stripped yet. You can then splice these bits of loom to your car, ideally using solder and shrink sleeving, shrink sealing crimps, or just to get you away, twist the wires and tape.
Alternatively, you could buy the generic solder-in replacement lambda sensor/s, extend the wiring that's left and fit some generic connectors. This obviously may have implications down the road if someone later tries to fit a replacement sensor with the correct connector.
Either way, you're going to have to be able to see what you are doing. Is there any way you could get it moved to somewhere more suitable?
