I am selling a virtually new Mallory 685 ignition box. My first box had some issues and was sent to Mallory and a brand new box was sent back. This new box was installed and tested but never used for a nitrous pass which was its intended use on my set-up. It was on the car for less than 100 miles. I am including my wiring harness that will reach from the front to the back of an f-body, I had the box mounted in the hatch area. All factory items and parts that came with the box will be included.

I also have the MSD 8876 harness that will easily integrate this box into the factory harness that I used on my set-up. I will sell this for an extra $15 if the buyer is interested. These harnesses reduce the installation time, reduce or eliminate cut wires, and allow you to quickly convert back to the factory ignition.
