Either way, you can take a multimeter, find two wires that are disconnected when the switch is off and become connected when the switch is on, and ignore the other wires

Thanks [FSF]Ian,

I figured there may be some redundancy involved, and you may well be right about some info being passed to flight computers too. I will simply have to test and see which ones do anything. I also realise that I have far too much length of cable and need to shorten it anyway, so will be cutting off the connectors any way. I will save them for posterity....
