2022 TRD ORP Old Fart question - stereo help

I am sure this has been answered 10,000 times already, if it has please kindly link to it.

I have a 2022 TRD off road prem with non JBL, with the premium sound package with 8" screen. I have a couple noob questions:

I am installing a JL 450/4, JL 1000/1, PPI deq.8, Orion HCCA 12", Focal Toy165 and 6x9s and a HO 270 alternator.

1. What wiring/speaker harnesses male and female should i use? Metra only has 2020 version, can i use those? TacoTunes, if so which one? I don't want to t tap if i don't have to.
2. Does anyone have a schematic or pic of the back of the headunit?
3. Is the OEM head unit called entunes 3?
4. Are there install examples on here that show how to wire through the firewall and down the sides of the SUV?
5. Where are you all mounting your amps? Under the seats or on the back of the seats won't work and i don't want an amp board.

I will take pics of my install process if there isn't any current ones of a 2 amp, DSP, alternator and speaker upgrade.

Thanks,
ALD

 

Seriously?

 

Yep. From what i read on here,
https://www.4runners.com/threads/he...all for 2021 4Runner without Factory Amp /JBL

They don't make a harness. Is that correct?

 

Good luck man. Not much support for 20+ systems.

 

Well i know people have done it, i watched the videos, They just don't iterate what harnesses they are using. Anyone?

 

You can check crutchfield.com to see what fits and they may be able to tell you what adapters are needed and may even sell them.

 

@crashnburn Thanks, i did that, they don't have 2022 speaker harness, they sorta have wiring harnesses but i am keeping my oem unit so i really don't need one of those. I am guessing Taco tunes harness might work but wanted to ask someone who knows first, they are like $79.

2022 speaker harness, they also have a headunit harness for 2022.
