I recently destroyed part of my combination meter by applying 12 v dc to the speed sensor wire at the ECM. I only had 650 miles on the car and searched the country to find a replacement meter from a junkyard. I finally found one that has 72 miles greater than mine. Do I need to do anything special during the replacement, for example swap a chip for mileage? When I called the dealer, they told me I would have to bring my car in, leave it, they would order the meter from the factory, it would come programed with the exact same mileage. I am not trying to be dishonest, as the replacement actually has a few more miles than mine. I can't afford to spend $425 to have the dealer replace it and be without my car for 2 weeks. This is for a 2007
