towing electrics legality?

You lot can argue till your blue in the face. I work in the industry and know the law!

 

Sorry your wrong see links for the MOT Manual

http://www.motinfo.gov.uk/htdocs/m4i00000001.htm
Section 1.9
http://www.motinfo.gov.uk/htdocs/m4s01000901.htm

the condition and security of the socket needs to be checked for both 13pin and 7 pin but the correct wiring and correct function only needs to be tested for 13pin

 

^^^This^^^
The Vosa inspector (he who checks MOT stations) lives down the road and he agrees.

 

lol. Ok guys

 

Can I just hang a red flag of me are end?

 

no - by law it must be an old dirty hi-viz vest.
