OBDSTAR F108 won’t read pin on 2004 Berlingo only Berlingo 2, download TDB007 manual it tells you which models work via OBD and which ones you would have to tap into the ECU wiring to get access to the CAN lines.
Then how to get the pin out for these cables?
It should just be the CAN lines… so on obd socket pin 6 CAN High/ 14 CAN Low
So really just need to be bothered to look at the pinout of all PSA ecu’s and the colours of wires for CAN lines.
Also I don’t like those connectors, you can get on ebay some wire taps that are just like a pin that goes through the cable(or just use a pin) then you can just use a few drops of glue to cover the small pinholes after.
Below is a sample hot to connect(for example Peugeot 307 non CAN with Bosch EDC15C2).
Red to green(CAN H) and Black to Grey(CAN L)
