Better with a 13 pin adaptor to double 7 pins if already fitted. 13 pin sockets are testable and failible on MOT 7 pin are not.
 
They can still fail on exposed conductors and on being cracked it's just the lamp operation for correct wiring that is checked on a 13 pin in addition.

That would come under general wiring condition or if the socket was obviously falling off by visual inspection. 13 pin are tested with a test plug 7 pin are not.
 
Right. Stand by your beds. I've tidied the hair ball up that was my wiring and paid attention to individual grounding. I put a bulb across pin 1and earth with LH blinker on the go and the trailer icon blinked on the dash. Therefore the caravans LED blinkers must be presenting insufficient resistance for the monitoring to believe there's no Caravan blinker. I'm reluctant to leave it at that as enough stuff malfunctions without volunteering. I might put a redundant bulb Somewhere after the tow socket. But that's my feedback if it's of use to all who've helped me. Best regards Peter.

Presumably if you were to fit an incadescent bulb then the blinkers and sounders etc work fine..?
 
You said a 7 pin wasnt failable on an MOT.

It is. You know that. You lied. End of now jog on and sniff some more of whatever the f*** it is you smoke when you are on here.

A 7 pin plug is not tested for function a 13 pin plug is. Since the last update any electrical wiring that is not secure or frayed can be failed. Any electrical component that is not secure can be a fail. Battery must be secured, before it could be loose fitted. Unless it had been wired by some complete idiot, towing socket wiring is contained within the socket by a waterproof gland, it is not possible to visually inspect the wires other than the outer sheath. As long as there is no damage to the outer sheath and the socket is secure a 7 pin socket cannot be failed. A 13 pin socket can if it fails the function test. I take it you have done a lot of MOT tests.
 
Are you now trying to say it can't be failed for a problem with a 7 pin socket?

Make your mind up.
You clearly can't read. If it is hanging off, it can be failed under being generally unsafe. If the wiring is badly frayed it can be failed for being generally unsafe. If it doesn't make the trailer lights work it CANNOT be failed on a 7pin.
On a 13pin,it can be secure and no problem with the wires but if it doesn't light the correct lights it will fail. How difficult is that?
 
Too difficult for wammers to understand. He was asserting a 7pin cannot ever be an MOT fail. As you and I noted it can if the wiring causes a problem.
