Perfect item that stops the cars brain having a fit.
Fitted this to my 2009 Ford Focus, so as not to upset the cars brain when I fitted my tow-bar, works perfectly and great price.

Maypole trailer wiring kit
It's a quality item but it doesn't come with any wiring diagrams so you need to know trailer wiring or do what most will do and look on Google

Tow item
Easy to fit despite no instructions with it so you may need to look online

Tow bar relay
Easy product to install, it makes installing a trailer socket to a car a doddle, it seems to be a good quality product and reasonably priced.
