Best Source For Ewd And Service Manuals

[RxVedub]

I'm having allot of trouble finding basic wiring diagrams like for the radio/navigation or backup camera.

Download for free would be great otherwise I will purchase a cd.

I would like the factory ones. Yes I know about TIS website but I want to have it on the computer or paperback.

thanks,

shant

Audio system diagrams are available on the EBSCO ARRC website - available at no cost through many public libraries. I've never seen general wiring diagrams for Lexus cars on the Internet or on Lexus forums where I have been hanging around for about 10 years. $15 for a 2-day subscription to TIS is cheap compared to the $250+ I paid for each set of manuals for my Lexus cars.
