Question

Question:

I AM TRYING TO INSTALL A SURE POWER 4 POST BATTERY ISOLATOR INTO A 1993 GMC 3500 VAN. FOR THE PURPOSE OF AN INVERTER. THE ISOLATER CAME WITH AN ADAPTER KIT THAT SEEMS OF NO USE FOR MY AGE ALTENATOR. IS IT OK TO WIRE THE ISOLATER THE WAY THE DIAGRAM , AND NOT PUTTING ANY WIRE TO THE E TERMINAL? THANK YOU,
