Mallory Ignition Sensor
by a Customer from Elizabethtown, Kentucky on October 27, 2013
The part works fine and seems to be well made but there are no instructions or pictures for installation and this part has an additional wire compared to the factory part. Also has extra screws and two black sleves, maybe protection for the connections? Hard to say what they are for.

Simplifies older unit
by Jeff from Lancaster, South Carolina on August 20, 2013
My original unit is a two piece, this is once piece. Simpler installation and perhaps simpler alignment.
