Tow/haul switch, brake controller

Hey, i'm new here
I am wondering if someone installed in 22-25 Tundra SR brake controller and tow/haul mode switch?
I planning to put OEM parts, but i can't find wiring. I tried to find something, also it shows something like "it's pretty prewired vehicle" and things i found are: don't need any additional ECU for tow/haul switch, but may be needed for brake controller
please help!
i really want to install both of them as of pulling camper and "7pin bluetooth brake controller" is completely mess, cuz i need to use another phone to let brakes work
i will greatly appreciate either pictures or detailed manual where are wires
thanks!)

 

Try and play around with that search function by clicking on more..it really does work well if you just give it a little effort to figure out how it works to narrow it down to 3ed gens...that being said.....

You don't add the OEM brake controller because the wiring isnt' there. You'll want to go aftermarket hardwired in or use the "7pin bluetooth brake controller"

You can read a couple pages discussing the matter here.

i greatly appreciate your help!)
so what i found - brake controller better to install not OEM, but i still didn't found nothing about wiring for tow/haul button
is it works like "plug-n-play"? is there any wiring somewhere around place of installation?

 

I linked you that answer too right above your reply
