Hi can someone tell me where the diagnostic plug is located on my 93 U300 Grand Villa 40'. Coach is being serviced at Detroit and I want them to plug the engine in to double check everything.
Thanks,
Woodie
Woodie,
The DDL should be located under the dash to the left of the steering column. It uses a 12 pin connection. If you are using a Pro-Link 9000 data reader you will also need a special adaptor plug 401003 to connect the DDL to a 15 pin cable for connecting the Pro-Link.
