Hi all. I own a 2013 Kenworth K270 box truck and I would like to connect a scan tool to the truck but all I can find is OBD2 Type A scan tools and not OBD2 type B scan tools. Am I missing something? Tearing my hair out trying to find a scan tool. Is there an adaptor available? I know that OBD2A is 12V and OBD2B is 24V but that's all I know. Any help would be great.
