    Rated 5 out of 5 by from Great looking Haven't put power through it yet because I installed it in a show car that's being built. Not only is it a one wire but after calling Jegs they informed me that by simply removing a rubber plug, the original wiring harness plugs right in. Very versatile. The chrome finish is perfect.

    Rated 5 out of 5 by from Better than expected Purchased this for my Boss Hoss Motorcycle powered by a SBC ZZ4. Needed a chrome alt and this was an exact fit and flawless. It even had a performance sheet showing it was tested. Great product at a fantastic price.
