Experts on wiring confirmation please

2018 Taco, Adding a small 4 channel amp to factory wiring and just want to get confirmation from someone that really knows what they are doing. Aftermarket HU so using RCA inputs. Asking because it seems just too simple that this is correct.

 

You nailed it!

 

it's what makes a toyota a toyota! it's one of my favorite parts of the truck!

illumination wire is optional as well-- most decks don't handle it great, i've skipped it my last few vehicles. just changes the brightness from "early morning" to "5-min earlier morning"

i also don't believe the blue remote wire needs to be ran into the vehicle-side harness, but it's not hurting anything either.

 

Thank you gentleman! Appreciate the responses!
