Installing Kicker hideaway sub... which of these are speaker wires and +/-?

I am installing a kicker 10" hideaway sub in my 2021 tacoma (non JBL). I need to tap into positive and negative speaker wires on the right and left side of the rear. The first picture is the right rear side and the second picture is the left rear. Which color is which? Been reading mixed things online

 

Maybe this:

 

Do you have a diagram like that for the front speakers?

 

Hi,

Kind of off topic here but I wanted to ask where you ended up mounting the hideaway? I've heard it can fit underneath the driver's seat? If it's already installed, does it do a good job supplementing the existing oem speakers?

 

I mounted it behind the rear seats. I through-bolted it and ran wires under the carpet to the door sills for battery, and used a self tapping screw near the seatbelt bolt for ground.

 

I installed component Polk Audio DB 6502 in the front and coaxial

Kicker 43DSC6704 in the rear. It all sounds great together, now working on installing a Kicker Key 200.4 with it all.
