T-One connectors allow for a quick connection without needing to splice, cut or tape your vehicle’s wiring. The installation is quick and easy with no tools necessary! Fits the following vehicles/models: 2004 - 2010 Toyota Sienna van (all styles).
Looks good to me. Instructions seem clear and have nice photos. I haven't yet installed it though.
Very user friendly
has not been installed yet so don't have an real opinion it just looks to be fine.
