Sorry forgot to mention on this thread.. iam trying to test the continuity from my bank 1 02 sensor plug to the plug pins at thd ecu end.
To be honest .. if you are only checking continuity ... basically resistance with no volts or amps, so using the meters internal battery... you can simply extend the leads by using any handy cable with an inch or so bared at each end, then wrap one end around the normal probe and secure with tape, the other end becomes a temporary probe.
Its a bit of a bodge but I have used this several times when checking things like towing harness continuity from the front of a car to the rear socket. I usually "extend" just one probe this way .. and use the other short one so I can read the meter/hear the beep (mine gives a tone with very low resistance ... very useful for continuity checking

)
I would NEVER use this for voltage / current checking .. ONLY for continuity checking
HTH
