Unilug Two Up Negative Lug Battery Terminal Kit.
 
Two Up battery terminal lugs are purpose designed for dual battery installations where it is not desirable to cut or modify the factory battery leads or terminals. The concept allows factory strap type battery terminals to be fitted to a special tapered adaptor at the same time providing an additional terminating post to connect auxiliary batteries and/or ancillary equipment.
