I've just picked up a used fixed towbar that came with a 13 pin socket but nothing more. Has anyone got a guide or knows of one to point me in the right direction. I spend my life doing wiring on boats but don't do much with cars since my days of giant subs when I was a teenager. If I can get all the functions of the 13 pin socket working it would be great, but I've no plans to get a caravan and will just be towing a small motorcycle trailer and probably a towbar mounted bike rack so don't really need the charging and fridge bits.
Does the accord need a bypass relay? I've seen the dedicated wiring kits but they're about £130 so probably a bit much for my needs.
