    Rated 5 out of 5 by from Nice wires Much better than the Jegs brand wires I'm replacing. These come with an adequate stripping/crimping tool to aid in assembly. These wires are very long, I used the shortest one supplied for my longest wire.

    Rated 5 out of 5 by from Perfect wires The wires were perfect. The instructions were thorough, and they came with a handy tool for crimping and cutting the ends.
