Please note that not all installers will install switches on all vehicles. For example, a Ford dealership may decide to only install switches on Fords. The National Highway Traffic Safety Administration has not certified installers as competent or specially trained to install on-off switches. Some installers have received specialized training from vehicle manufacturers on proper installation; others have no specialized training. Any questions regarding training or willingness to install switches on a particular vehicle should be raised with an installer directly.
