THIS AUCTION IS FOR ONE IGNITION CONTROL MODULE. WHY PAY $100 THRU GM WHEN YOU CAN GET ONE HERE CHEAP! IF THERE IS ONE SPARE PART YOU WANT TO HAVE IN YOUR GLOVE BOX THIS IS IT! BECAUSE WHEN THIS ONE GOES CALL A TOW TRUCK YOUR NOT GOING ANYWHERE. ITS EXTERNALLY MOUNTED NEXT TO YOUR IGNITION COIL SO IT'S VERY EASY TO CHANGE IF YOU HAVE TO. I ALSO HAVE OTHER CHEVY / GMC TRUCK ECM COMPUTERS AND TBI FUEL INJECTORS AND SENSOR SETS FOR 2.8 4.3 5.0 5.7 AND 454 LITER ENGINES UP FOR AUCTION IF YOU CHECK OUT MY OTHER AUCTIONS. PLEASE VIEW MY OTHER AUCTIONS FOR MORE CHEVROLET FORD GMC DODGE TRUCK PARTS. THANKS!!!!
