    89618 - MSD Relay and Wiring Kits is rated 2.8 out of 5 by 4.
    Rated 5 out of 5 by from An excellent relay!! Price was great, and quality is great. Plenty of wire, easy to install. Not sure what gauge the power wires are, but they are large and flexible. Very pleased with this MSD product.

    Rated 1 out of 5 by from Bad relay So I wired everything up and when the power was turned on nothing happened? Went to the local auto parts store and bought another 40 amp relay and everything worked as it should. Took the Msd relay apart and the grounding wire inside was never landed on the post from the factory!
