Simple and Effective
Nice solution and easy to wire up, saved me sourcing the dedicated kit (Which was more expensive and very long delays in ordering) Instructions were clear, and all worked fine the first time post installation.

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

Non è male, si risparmia rispetto ad una centralina canbus, ma da fastidio il bip alla retromarcia

Instal.lat en un renault laguna substituint el mateix model. Porta feina la instal·lació però els llums del remolc ara van bé. A més aquest model fa uns pitidos els intermitents quant està el remolc connectat
