04 Double Cab with JBL "Premium" Sound wiring diagram??

I'm new here, mainly because I just bought a 2004 Tundra Limited Double Cab, and I am needing some assistance. I recently purchased a new HU, Subwoofers, and Amp to install myself, but I seem to be having trouble locating a wiring diagram for the JBL sound system. I have the double cab, with the Amp located behind the rear seat on the driver side, and I do plan on bypassing the Amp. I am pretty savvy when it comes to auto electric and audio, but this Toyota sound system has me just stumped. I think I have spent hours upon hours searching for the complete wiring diagram. I don't want to pay for one, then it be incorrect. (Learned my lesson after paying $14.99 and they didn't have anything on my truck at all, when they had it all before I paid! What a scam!! I did get refunded though.). Can someone please point me in the right direction?

 

Did you look here? Should be everything for the entire truck directly from the Toyota Technician Portal.

@RainMan_PNW does a great job providing this info. Big thanks to him.

Pay attention in the diagrams for the first gen trucks - the RC and AC sections are separate from the DC sections, and the DC are grossly different in many regards.

 

Here's a link to the first gen amplifier thread as a start. Link
May have better luck posting in the regular 1st gen section too.
What is your plan once you find a wire diagram? I believe they make amp bypass harnesses you just plug right in.

 

Since I have an 04 LTD DC also, the attached pdf is what I used from the 04 EWD when installing my aftermarket. The whole EWD mentioned above is definitely good to have also.

Have also attached another RSES Audio System pdf where I combined the applicable pages. Once opened in Adobe or whatever for pdf's. you'll have to zoom in to view but it was readable enough for me to complete my task.
