Hi,
I attached the wiring schematics below for the two radio options the vehicle came with. One had a power amp and the other didn't. Note that each system was one page long. I had to cut each in half to make them readable for you. I did overlap each so you can follow from one to the next.
The first two pics below are for the OEM system that had the amp. The last two are for the one that didn't.
I added both so you have them in the event you need to identify other wires. Also, from what I'm seeing, regardless of which system you have, the wire should be dark blue.
Here is a link that you may find helpful:

Let me know if this helps or if you have other questions.
Take care,
Joe
