And inside the box... The Howell harness and black box that I got years ago. programed without VATS, EGR and 2nd o2 sensor. Set up for 35" tires and 4L80E which Im going to have to figure out. Whew! Was really sweating that I couldn't find it. Also found the original black box and harness that came with the engine. It was under the house.
