Universal digital harness for cars

This set is the first choice for the supply of all 12 Volt devices in e-mobility vehicles and for the restauration of classic cars if you need to change the original harness due to it´s age.

The E-Harness contain a dashboard control module and 2 power modules what control the 12 Volt power to all lights and other 12 Volt devices in a car. All switches and buttons at the dashboard are connected to the dashboard module. The modules "talk" via a small 2 - wire data line. The main power to the modules is supplied from the dashboard module when you switch on the ignition switch. The 2 power modules are identical and are installed at the front side and rear side of the car. A small bridge against ground decide if the modul is mounted at the front side or rear side. Almost all power outputs are short circuit protected and self resetting after the short circuit. This reduce the dimensions of the fuse box. This digital harness saves more than 100 meter cable in a typical car installation. The length of the power cables to the lamps are shorter and the installation time is shorter as well compare to a "traditional" harness.
