Stereo Wiring Help: Wire Colors Not Matching

Hey guys. I'm installing a second amp to power my door speakers. The LOC for my sub amp is currently tapped into the Front speaker signals. I wanted to tap into the Rear speaker signals with the second LOC, however my wiring colors for the plug that carries the rear wires appear to be different that every diagram or picture I can find. Even other 2017 Non-JBL Tacomas have different color wires than me.

The Front Purple Wires are the same, but for the Rears - Where everyone seems to have White/Black and Green/Blue, I have Black/Tan and Blue/Grey. Pretty positive I am looking at the right plug and have no other plugs with the White/Black Green/Blue sets of wires.

 

Don’t use the rears. Tap the fronts again

rear speaker signal is TRASH. Hardly any bass exists, and the volume level to the rear speakers is almost entirely useless

 

Will do. Thanks for the reply
