Hello All,
I purchased the 1999/2000 parts and service CD (AM General original) but it does not have the wiring diagram on it. The 1997/1998 CD does but the wiring is not the same. Where can I get a set?

It should be in the service section, if there is a specific area that you need, let me know and should be able to send you a copy..
