Thanks Slowmax.. had a good look around, it does have hitch but can not see anything that looks like that..... been under truck with torch for 30 minutes grrr
Looks like I'll have to hard wire off my tail light wires, but the four wires is throwing me to be honest as its simply brake light and running lights, so I'd have thought three wires? 2 lives and 1 earth? but I'm no electrical expert lol!!
