2003 Radio Harness doesn't fit???

Hey I have a 2003 toyota tundra and the radio harness that I got to swap out my radio to an after market doesn't connect to the one that came off the stock radio. I have pictures attached. For everything I can find online, i can't find any sort of different harness for a 2003 so I don't know where to turn. I was hoping it would be just plug and play but I didn't get so lucky. I tried the search bar but I couldn't find anything. See pictures attached and let me know if you can help or know which harness I need to buy?? Thank you in advance!

 

DONT YELL AT ME. Lol I ended up finding something using the search button the CORRECT way lol.

I'll update if it ends up working!

 

Does your truck have an amp? Which model, sr5, limited?

You may need this harness. No the one you have.

It worked great! Just had to remove the truck amp and the harness worked perfect!

 

So where did you plug the harness in at? It look like it doesn't fit the factory plugs behind the dash.

 

There is a factory amp installed in the dash that you have to remove and then the harness fits into the wiring going into the amp.

 

Oh, i see. Hidden away i guess.

 

Okay, I have this similar problem and the harness connections have the same difference. However, I was transferring my 02 radio to and 03. Will I be able to bypass this using the amp connectors as well?
Second question...I have more space in the dash. Is there a harness that is set up to fill that space? I was told my stock radio would be interchangeable so that is what I am doing for a friends dad since he doesn't need a 'fancy contraption". Any ideas how to remedy the two issues is appreciated!
