Heated seats other than Limited?

LarryM04 · Mar 21, 2014

I'm shopping to replace my Trailblazer and the Tachoma is at the top of a very short list. I live in Tenn now, but only recently move from Ill, where heated seats are sooooo nice to have. I see that the Tachoma has them, but just in the Limited.

I took my wife's Prius to the local dealer to get the oil changed, and took the time to talk to one of the sales guys while I was there. He told me they can put heated seats on any model. I was surprised and meant to ask about it, but had so many other questions, I forgot.

I assume this means they take the existing seats apart and add heating elements and NOT that they take the seats out and put whole new ones in.

Has anybody done this? Had the dealer add heated seats? Are you happy with the results?

Hmmm.... I'm not aware of a 'heated seat' option on any Tacoma's other than the limited. But they are easy to install. Your dealer can do it or you can go to an auto sound/alarm shop to have it done. By the way, it's 'Tacoma' not 'Tachoma', just FYI...

My plan is to put seat heaters in or get the seats reupholstered and have the heaters put in at the same time.

Yes, had dealer put heaters in my seats on purchase. Cost $500 for both, but I think it was a mistake on the qoute, as my son and daughter in law bought a truck from the same dealer a month later and were quoted $1000... they have worked well so far, I have owned the truck since January 2013 (bought new). Switches are in the little blanks in the lower center console. I say go for it...

They sell aftermarket kits that you can install yourself.

the biggest reason I went with the limited over the offroad. I will use the heated seats more then a locker.

There is a local auto sound shop in Columbus, OH that is running a special for seat heater installation for $149.00/seat....

My TRD Sport came with them from the factory.

Of course, we're in Canada and we really like them

" YUP " the TRD sport Canadain model comes with " pleather " heated seats as an option . Mine is a 2010 . Not sure about the newer Canadain models .

Started in 2008 I believe

Just spend the money on a set of wet okole seat covers with the heated seat option. Probably way cheaper than getting them installed under the existing upholstery. Also - you get the awesome seat covers.

smgcon · Mar 21, 2014

My Canadian TRD Sport has heated cloth seats. The Limited has the heated Pleather up here.

Vantage · Mar 21, 2014

You now get heated seats standard on the CLOTH sport seats as well in Canada.

I just got my new Tacoma this past week, and am considering those covers (I missed the group purchase, I think.. :-( ). How are folks wiring them in for +12V?

bgood · Mar 22, 2014

I had the dealer add them to my 2014. I think I paid $500 installed. I didn't want to do it myself. I think the elements themselves are around $200. They work and I didn't want to step up to the Limited to get them.

bowhun2r · Mar 22, 2014

Love the heaters. Probably my favorite mod on the truck besides the S/C. Even when it's warm out I put them on low....works wonders on my back.

Since when ? It was an option on my '09 TRD Sport

$500? $1000? For installing seat heaters? I think I'm in the wrong line of work.

$89 per seat for the regular Warm Seats (OEM for many car companies). Comes with a back pad and a butt pad, wiring harness, relay, switch with a high/off/low setting:

http://www.jegs.com/i/Warmseats/936/WSH/10002/-1

The only tools you'll need that you likely don't have are hog ring pliers and hog rings, which you can get through Jegs for $14:
http://www.jegs.com/i/Dorman+Products/326/74366/10002/-1

Then, plan on a nice quiet evening to get the pads into the first seat, quite a bit less for the second seat. Wiring took the longest and that was mostly trying to figure out a good spot to put the switches and route the wires. Here's a writeup I did on another forum when I put them into my truck (yes, it's in 1st gen, but I can't imagine seat technology has changed that much)

By popular demand, here's a quick rundown on how I installed a set of WarmSeat seat heaters in my '02 Toyota Tacoma. I ordered the seat heater kit from www.JEGS.com, but if you search for WarmSeat heaters on the internet I'm sure you'll find other sources. I went with the waterproof model, which as you'll see was a good idea in theory, but not so good for my application. I'd have saved a couple of bucks if I went with the regular ones.

You'll need a pair of hog ring installation pliers and a pair of diagonal cutters for this part, along with whatever tools needed to remove your seat. For the electrical work, you'll need whatever connectors necessary to tie into your particular electrical system (I used appropriately sized ring terminals).
If you have a side airbags or airbags that are mounted in the seat (newer vehicles) you're probably better off taking it to a professional. If you've got an older rig or no airbags in your seats, carry on:

First up, remove the seat. Not too difficult, but be aware that there may be sensor wire connections you'll need to disconnect, like the seatbelt unbuckled warning light wire on the driver's side of the Tacoma.
Next up, you'll need to get the upholstery off of the seat. I decided to start with the bottom cushion, and in order to take the upholstery off, I first needed to remove the plastic trim. I can't really describe how to do that other than to say that it's sort of a pull/twist/shove all at the same time on the Tacoma. If you have a factory service manual, they usually have an exploded diagram of how things fit and what can be disassembled and reassembled. Here's a shot of the passenger side with the plastic cover removed, the bolts for the seat pan will be obvious since they do nothing other than hold the seat pan on:

Trust me when I say that you'll want to avoid hitting any of the recline levers while the seat is out of the truck.
So, now you've got the lower seat cushion off. Flip it over and have a look see at the bottom. It probably looks something like this:

Astute observers will note that the bottom of the seat is still attached to the frame in this picture. That's because it's the best picture I have of the underside. I was mostly taking pictures so that I could see how things were supposed to be when I put it all back together. The upholstery is held to the seat by small metal rings called hog rings wrapped around a piece of rod in the fabric. Using a pair of diagonal cutters, remove all of these hog rings around the perimeter.
Once all the perimeter hog rings have been removed, you can start removing the upholstery. You'll find that the top of the seat cover has more rods that are clipped onto rods embedded in the cushion with hog rings. The lower cushion on my truck had one rod going across the seat and two running parallel with my legs. Here's a view of one of the parallel upholstery tie-ins. You can see the hog rings (red) and the rod (green):

I snipped those last hog rings and removed the upholstery completely from the cushion. Now, it's time to get the seat heater ready for installation. The heater pad fits between the parallel upholstery tie-ins mentioned above, but you're going to have to get it to go underneath the rod that goes across the width of the seat. To do this, you'll need to cut some holes in the heater pad (see why I could have skipped on the waterproof ones?). This isn't a big deal so long as you DO NOT CUT the leads that run down the sides of the pad. Cut those, and the pad is no good. I marked out the leads and location of the fold that needs to go under the rod going across the width of the seat (believe me, it will all make sense once if you decide to take this on):

Here's the bottom heater sitting on the foam pad. The sharpie line marking the fold is pretty obvious. The other sharpie lines are the electrical leads that you're not supposed to cut:

Now, along the sharpie line for the fold you'll need to cut two holes about 1" diameter to allow the hog rings to pass through and hold the seat cover to the seat cushion. After I cut the holes I lined the edges with electrical tape to insulate them from the hog-rings. Then I put the seat cover on and hog-ringed it to the cushion, then began reinstalling hog rings in roughly the order I took them apart. This is where the pictures end. The hog-ringing wasn't difficult and the initial pictures were taken more as a reminder of where to put things in case I ran into a snag. Once the lower cushion was back together I removed the seat cover from the seat back. This was even easier. There was a clip along the bottom edge of the cover. Once I undid that, I was able to shimmy the cover up the seat back til I hit two hog rings going across the width of the back. Snipped those and that was it. I saw no need to remove the cover completely and I installed the seat back heater in the same manner as the seat cushion heater: cut a couple holes for the hog rings, cover the edges of the hole with electrical tape, install new hog rings, slide cover back down and fasten clip on bottom. I reattached the lower cushion to the seat and reinstalled it in the truck. I worked on the seats over two evenings. The first took about an hour, the second took about 30 minutes.

Once the seats were prepped, I started wiring up the the truck. The wiring harness looked to be decent. The instructions for wiring were anything but. I ended up drawing out the wiring harness just so that I could see what was doing what with the relay and switch. In the below drawing, the left side is what came from the factory. The white wire goes to a ground somewhere, the red wire comes from a source that is switched on with the ignition. I didn't like the idea of adding a potential 10amp load to existing accessory circuits that had 15amp fuses, so I opted to to a different route. To the right of the drawing you can see the addition that I made by installing a relay and a piggy back fuse. The relay closes when the ignition is switched on, providing power to the seat heater circuit. Not shown in the drawing is the supplied fuse installed between my circuit and the original circuit. There is an additional 20amp fuse between the fuse block and the relay. Also note that the drawing is for one seat. The other seat circuit also comes off of terminal 87 on the relay I added and is identical to what is already shown.

Once I figured out how and where I was going to make the connections, it was time to start actually running wire. I mounted the relays for each seat heater underneath the center console and ran the wires out the sides to the seat heaters and forward underneath the consoles to the switches. The switches are mounted on the trim below the ash tray:

The relay I added, along with the piggy back fuse and my aux fuse block are located under the driver side dash.

All in all I wouldn't say that this project was terribly difficult. There was definitely a bit of worry initially dealing with the seat upholstery, but in my case it all was very straightforward. I didn't do this project with the intention of also doing a write up. I would have taken many more pictures if that had been the plan. Unfortunately, I was in a bit of a hurry to get the job complete in time for a trip.

Hope this doesn't create more questions than it answers

I'll soon have a 2nd gen and this will be one of the first mods I do. My wife absolutely loves it. She's been nagging me to put them into her Corolla as well. You'll need literally two evenings to get the pads installed in the seats then an afternoon to run the wires.
