It works great. had it installed on the car all summer. Put on close to 2500 miles. I used a set of 8mm Belden plug wires from NAPA. I think they were for a Ford.I chose to buy premade wires instead of making my own. I can get the part number and application of the plug wires tonight if you would like.
