Re: Add-A-Circuit switched power?
Have you looked for that info in your Alldata manual? If it's not there, electrical info should be available in the service manual - probably for factory-installed DVD players. There's a link to a file download for the manual in several threads of this forum.
for "manual download" and be sure to use the quotes. Good luck!
Also, look through the forum for threads about finding switched power near the overhead console. That could be an option for you.
