Aftermarket SR5 Heated Seats Install?

[JasonNewYork]

This was one feature I really wanted and the dealer was asking $1,000 for an aftermarket installation. Besides the ridiculous price, the installer placed a rocker switch on the seat bottoms facing the doors. If I were to go this route, I wanted the switches in the center console.

Long story short, I came across a company call Clazzio. They sell a kit that comes with 22mm square switches. I believe this is same size switches for both the dash and center console.

Anyone have experience installing heated seats? I searched for both 6th gen 4Rs and 4th gen Tacos with no luck. Wondering how hard is it DIY? How do I wire it into the truck? I'm very handy but also do not want to damage my truck.

I'd shop around. Give your local car stereo / tint shop a call and see if they install them. I had mine done for $600 using the round rocker switch in the link you provided in the center console. The $600 was through the dealer which had a local custom shop do it. Had I know that the dealer would hire out I would have just gone straight to them and avoid the dealership taking a cut.

It probably isn't terribly complicated to install yourself but I wasn't going to start my learning process with something like this on my brand new vehicle. Also, it was worth my time to have someone with experience do it.

And not to be confused with the buttons where the rear locker and camera buttons go on other trims - this is what I meant by center console.

I just installed the Clazzio heated seats in my 2025 SR5. The install is not bad at all. The wiring is what took me the longest. These work great. The switches fit right in the console.

That's not bad looking at all. I want to be able to see if they are on in case my son forgets to turn his off . I think IF I were to do this, I would go with the kit in the link above. I like the idea of factory looking switches. Thanks for sharing.

Canadian sr5 comes with it standard, probably due to our weather

How much did it cost?

 

[slamkad]

The Clazzio seat heaters were $180. I then spent around $50 in wiring and fuse parts.

Slamkad - that looks awesome - the button placement is exactly what I had in mind. How did you figure out how to take apart the console and wire them up? How hard was it to dissemble the seat upholstery? Do you have any pics or links with instructions. This would make a nice DIY post on the forum. Any help greatly appreciated!

I did not have any instructions on disassembling the console. The part the shifter is on just pops off. Then I removed the 4 bolts in the bottom of the storage area in the center console. There are 2 additional bolts for the console under the part that has the shifter on it. I also removed the piece of the console on the passenger side that I would call a handle. It has 4 bolts. You have to remove 2 dash pieces to access 2 of the bolts.

You need to connect 4 wires for each seat. Ground, Illumination, Ignition on, and 12v. Illumination I tapped into the wire that turns on the light for the shifter. Ignition on I used the wire on the cigarette lighter port. 12v I installed 2 add a fuse in the fuse/relay box on the left side under the hood. I took the wires into the cabinet through the boot for the speedometer cable.

The seats come out with 4 bolts each. There are multiple plugs that have to be disconnected once you unbolt the seats. With the seats out, remove the plastic around the bottom of each seat. Remove the 4 bolts holding on the back of the seat. I am used to hog ring holding on the seat covers. The new Toyota’s use some kind of new plastic clips. The upholstery comes off fairly easy. Use a small screw driver to assist with taking the upholstery plastic out of the clips.

Hopefully that helps. Let me know if you have any questions.

I just watched two videos, one for the shifter and the other for the center console removal. I see what you are talking about. Thanks for the tips. I'm curious what the plastic hog rings look like. Sounds like it's a lot easier to do on a modern Toyota.

My only real concern would be splicing into the factory wiring and the warranty. The owners manual does show two fuse locations in the block for heated seats. How hard would be it be to tap into those? My dealer told me their shop (a local Katzkin dealer) does all the wiring from under the seat. They use the round switches from a universal kit and install them on the seat bottom plastic. I suspect they are either tapping the lumber power or existing 12V+ in the harness.

I would not call it a plastic hog ring. I could not find a picture of what it looks like.

I did not cut any of the factory wiring. I used Posi-tap connectors. I would suggest anyone else do the same.

I just picked to spots in the fuse box that were not being used. It’s possible they used wires under the seat. I wanted dedicated 12v wires ran for each seat.

I just googled the Posi-tap connectors. Those are cool. I'm used to the old splice taps that destroy the wire insulation and sometimes cut strands.

I agree it's best to use a dedicated circuit when available. With any dealer, speed is key to profits. Based on what you told me, the Katzkin place prolly gets it done under 2 hours since they do all the work on the seats only.

I just spent a few days in the Adirondacks NY (near Canada). Would have been nice to have heated seats in -7F weather. My windshield washer fluid froze too. I'll tackle this project when the weather warms as we get closer to Spring. I now have a lot more confidence thanks to you.
