my bud has a 02 Dakota with a 5.7 Hemi swap. The engine is running great with an 05 ECM from a Ram. everything is working OK except he is getting a ABS light on the dash and flashing led light on the AC panel. we are thinking that the Dakota body and ABS module is not happy with the 05 Ram engine module. I found a guy that can change the VIN# on the modules, will this fix it?

Any ideas?
