How to read MC68HC705B32 (UCH) on the Megane in circuit with Iprog programmer?
the diagram that the iprog says it is to read the processor, but the cable from pins 1, 5 and 40 has no connection and as the wire cores are not like the diagram.
Get a multimeter and test what colour wire goes to each pin on adapter then write it down
then you will see what colours corispond to the colours you need if there then found to not be connected to the pins you need then get a soldering iron and move the wires to the correct pins
if you cant solder then get someone who can to do it for you.
