The Model 7 electric/hydraulic boom is activated by a set of 25' 4 gauge cables (included) that connect to the unit with a weatherproof plug.
The remaining cable is then run back to the batteries on the towing vehicle thus providing power to the boom. These cables feature 600 amp heavy duty clamps and a protective cable sheathing that stays flexible in sub-zero temperatures.
