After the 600 mile run at the weekend I was well and truly fed up with constantly hitting my left hand on the sat nav charger every time I changed into 5th gear so decided it was time to make one of these, bought the duel charger from Aldi for a couple of quid and pulled it to bits and fitted to a blank, sods law, I can't find the super glue, I will take it to work tomorrow glue it all together and solder a couple of wires on to it, whats the best way to wire it in and which connection is positive, thanks
