Thanks, I was a premium member last summerand got shop manual on this site but 08Electrical Subsection 05 (The Dess Digitally Encoded Security System), Subsection 06 (MPEM Multi purpose electronic module), Subsection 09 (Instruments and Accesories) and Section 13 Subsection 01 (Wiring Diagrams) pages say " The information was not available at print time. To be published later." I thought it should had been included in the download and it would help with troubleshooting.
