I currently have a Rolec Type 2 charger with a tethered charge cable. I now have an Ohme add-on smart cable which requires an untethered Type 2 socket at the wall charger end. I can get the Rolec parts to do the conversion (basically the socket and a mounting plate) but I'm not sure how the wiring of the socket should be done. Also helpful would be the correct spec. of the stranded brown, blue and green/yellow cable required for the internal mains wiring.
