1999 Chevy S10 with a 5.3 engine and a 4l60 trans. It runs great!! the harness was professionally made to work with this truck. so everything works as it did from the factory. all the gauges work as they should. it has 2 inch drop spindles in the front and 3 drop blocks in the rear. it has wheels and tires off of a Z06 C7. its a cool little truck! might trade for a SHORT BED SQUARE BODY. $8500
