I HAVE A 02 DODGE 1500 4DR 4X4 WITH THE 5.9 THE DEALER SAID THE INSTRUMENT CLUSTER NEEDS TO BE REPLACED. INSTEAD OF PAYING THE BIG BUCKS AT THE DEALER. I SEEN SOME ON EBAY A LOT CHEAPER.NONE WITH SAME MILEAGE THO.DOES THE COMPUTER JUST RESET THE USED ONE BACK TO YOUR ORIGINAL MILES OR DO I HAVE TO DO RESET THE COMPUTER.OR WILL THE USED ONE JUST SHOW SAME MILEAGE.ALSO IS THIS A EASY TASK TO CHANGE.
