If the pins look like they’re rusted, have green copper corrosion or are bent beyond repair, just replace the plug. If they are carefully bend them back into position. Once it’s all washed out, connect and disconnect the plug 3-4 times to further improve the connection.ĭoing this simple clean will ensure the trailer doesn’t lose connection while you drive, this is especially important as the trailer plug is also supplying power to the brakes on the trailer and you don’t want to lose those! Whilst you’re there checking the trailer plug, grab a small flat head screwdriver and make sure the pins aren’t bent out of place or pinched on either plug. Make sure you do the same to the trailer plug and socket on the tow vehicle too, just to be sure.
