This guide will show you how to install the RUV Electrical harness in a Sprinter 144 (2007+).  

It takes about 2-3 hours for first timers to complete the install.

We have included all of the necessary wiring, connectors, fuses and breakers to power the lights, fans, USB and 12V jacks.  

In addition we provide cabling for additional accessories like a diesel heater or electric awning.

The electrical kit is installed in two phases. First we connect up the harness from the battery along both sides of the van.

After we complete the insulation step we then prep the wall connectors for lighting, fans, USB and 12 Volts accessories
