lambda wiring

[hoppo4.2]

Someone has made a right old mess of the wiring on my sensors.

The plugs have been cut off and some shocking crimping has been used but also the 2 sensors have been joined up some how.

They are both reading 0 or 0.1 v

I've ordered some proper connections but I could do with a diagram to check where each wire should go and to pin it out back to the ecu.

Thanks

That would be a big help thanks
