@RainMan_PNW linked the full wiring you'll want. In addition, if you want to look at just the audio/navigation system, this should be the link for a wide PDF of everything in the audio/navigation system: https://www.tundras.com/attachments/2008-separate-amplifier-pdf.1034727/

 

That's a sweet PIC of all in one place. The difficulty is reading all the code.

Here's a Hint (perhaps TMI for the OP):
Circled Letters refer to Named Plugs within Component where the same Letter appears in parentheses.
You then must refer to the Section where the book identifies the Plug in alphabetical order, with shape and # of Pins shown.
Any Plug used in the System for even a single will appear at the end of the section.

Rectangles are Junction plugs and for these you have to Research the Location tables.

A good example:
If you have a Navigation system, you'll find PKB (Pin 1) and REV (Pin 5) at the K6 Plug on the back of the Receiver. (Circle F with footnote *1)
If you do not have Navigation, this plug doesn't exist:
PKB is at the Foot Lever and REV is at Junction J77 (which after much location research -- is under the electrical tape wrapping the main harness at the dash support main beam, behind the radio to the right -- look for the big boxy lump -- that's J77, and the Location tables are so complex in this area it's nearly impossible to find -- except I just told you where it is.)
