Putting 2021 Power seat into a 2017

@Shveet was the person who actually swapped it to be clear, I was just the middle man lol. I did see it in real life when it was done, works like factory!

 

Just wanted to update y'all: Successfully converted to the powered seat last night and everything works factory. I did it a little different than y'all and only ended up needing a 15A fuse for the seat to function with power adjustments.

I can't thank y'all enough for your help! Feels like a brand new truck with these seats in there. I will be making a full write up with pictures today. In reality, it's ridiculously simple. Legit - it's just the big pink wire for ground on BA3 Pin #1 (6 wire large white plug on seat) and the large black wire for power Pin #5. I have a little harness that has a switch that lets me cut power to the motors of the seat so it's not always live straight to battery in order to protect truck from draining battery. Otherwise, everything was plug and play! Works great! I'll make my full write up post later today. Thanks again for all of your help.

 

Amazing… I Appreciate you reviving my interest in this! If I ever track down a seat I’ll probably hit you up and pick your brain

 

that 1H connection isn't connected to his 15A fuse.
the iE5 connector is bypassed and is connected directly to the OEM harness that the manual heated seats have, which is already fused to 30A.


The 15A fuse he has is for the motors driving the seat functions (forward, back, lumbar, leg support, tilt.)

 

100% correct.

All seat warmer wiring is 100% just the OEM harness, nothing changed. The only thing that I did was isolate the big pink wire and big black wire from BA3 on the seat, which I hooked up to a separate 15A fuse. Connecting my own aftermarket wiring or using a wire tap (hahaha no) on a 30A source had me too worried of fires, especially if always live.

 

I got a power seat out of a wrecked 2023 SR5 with 800 miles on it. I just switched the entire assembly from the wreck onto the frame of my 2019 leather heated seat, ran power to the fuse box and grounded it to the frame. It has worked perfectly since I did it in April of this year. I found the wrecked trucks seat on the website the member who originally posted this thread used. The power seat makes all the difference in the world comfort wise in my opinion.

 

Hey guys, I made my full walkthrough and post! Thank you to everyone who posted info on this and helped! Super happy with my seats!!!! https://www.tacomaworld.com/threads/how-to-install-powered-seats-in-2016-2019-tacoma.865681/
