I needed this on a 13pin system - the manufacturer's wiring loom had cable provided for grey pin 10 but no facility for switching power to it. Annoying but solved by adding this from the power supply cable to the tow wiring loom's lighting relay device (I left the permanent feed cable to pin 9 as it was). The relay was switching off at 12.7 volts and not their recommended 13.2V so I reset it with the screw - fine so far
Yes it will fit if you already have a towbar with a flange that has a towball bolted to it. The bolt diameters and hole spacings are standard in the EU. The nuts are very tight and usually rusted, however, and can be extremely difficult to undo.
My tow vehicle has a 7 pin tow plug - but I need to tow a caravan with a single 13 pin socket. Will the 13 to 7 plug in adaptor do the job? If not what do I buy? Thank you.
Yes it will do the job, but you won't have power for the fridge or caravan reversing lights if that is important to you. Make sure you have the correct adaptor with a 13 pin socket and a 7 pin plug which fts into your car's 7 pin socket.
