400 Amp Fuse and Holder The 400 Amp Fuse and Holder The (FUS-LINK) should be installed as close to the battery as possible using 1" long 5/16" #10 screws. The firewall or the fender well are possible options. Connect one terminal to the battery and one to the solenoid using #4 or #2 gauge wire (note: these connections are shown in the photo but are sold separately). We recommend using the FUS-LINK with PIERCE electric winches. Replacement parts: (ANL-400) Fuse ( 4164FR) Fuse Block
