Hi guys I have a 2002 1500 4.7 quad cab that the previous owner did a front end and dash swap to a 2006. THE ECM IS READING FROM A 2006 ram truck but it is an 02. the truck is in limp mode all lights on. Just running rough. NEED HELP!!! Was told that the tcm or ECM needed to be replaced in order to fix issue but the dealer won't touch the issue because of the swap saying the difference in dash and front clip is a liability for them concerning air bags. Please help!!!!!
