			I have been a heavy truck mechanic for 15 years and that has changed a lot to  i can remember to days before hooking up a computer to them the new freightliner have 4 ecms. 
Cars and trucks are differeant all togethere trucks are still sae and cars are metric and most the things are easyer to work on and get to except the wireing.
