Toyota 4Runner SR5 2022 speaker wires

Does anybody knows what colors are the speaker wires for L+, L- and R+, R-. to connect a subwoofer and amp with High input level, due to a lack of RCA output on OEM head unit. And do you think will be fine to just add a relay with a rocker switch to activate the remote on the amp when ever I want the subwoofer working. Thanks!!

 

Ok if there's anyone looking for this info I did a High level input with the wires of the head end the las black 10 pin conector has the 2 speaker wires needed purple + FRight, pink - FRight, Light Green + FLeft, Blue -FLeft and in the next 30 pin conector there's an accessory wire a gray wire in my case. Pin 17 I believe, didn't need to add a relay and a switch since I found the accessory wire. I installed a Rockville RVS12A and I have crisp clear sound with nice bass.
