Diesel RELAY Install for INVERTER

Here replacing a high amperage manual switch with a high amperage relay on my 2012 RAM Cummins Diesel. This will have a signal wire coming from my AUXBEAM switch controller which is already installed. IDK if this new inverter will cause a parasitic drain like my old one did, but the relay will prevent that, and also will help ISOLATE the majority of the 2 gauge wire for safety.
