AllDataDIY should have it. I have a subscription for my 1991 V2500. It cost around $25 for the first year. I just renewed another year for $9.95. I have had no problems finding some of the more hidden wiring diagrams on that site. I just recently had to find the wiring for the TC lockout from the ECU and brake switch - easy peasy.

Here is brief from their site:

• Manufacturer repair procedures and information
• Factory Maintenance Schedules
• Factory Recall and Technical Service Bulletins (TSB's)
• Illustrated Diagnosis and Repair Procedures
• Diagnostic Charts and Trouble Codes
• Component Locations with Diagrams

that's a great idea I didn't even think about alldata, so can you access it from any computer once you purchase the subscription or is it only from one device?

Yup, any computer. It's a username/password based web portal. I have been able to print off all the diagrams I have needed so far. I think most of them are GIF based, so you can save them off to your PC with ease.

I also been able to convert them to PDFs as well - but that is a function of installed PDF software and not their portal.

Here is a diagram that I pulled down when I needed to review the DRAC wiring.
