A tractor mechanics dream app. This app provides a remote user interface by connecting via Bluetooth to a 7-way power cord physical testing device. The testing device is hooked up to a 7-way power cord along with 2 air cords coming from a tractor (truck). This app allows the mechanic to stay in the drivers seat, test each of the tractors operations, and see the results on their iPhone or iPad. If interested in utilizing the testing device & app, please contact Electric Solutions at: http://electricsolutionsllc.com/
