doesn't get that cold here to me. But what does get cold here is my PIZZA. I live out on a ranch and it is
a 15 mile ride into town to pick up a pizza. By the time I get back to the ranch the pizza is cold. I had to do
something to take care of this problem. Enter Universal Seat Heater. I bought a 18 inch pizza bag on Amazon
and installed these heat pads inside the bag. Hook up a 15 amp cigarette lighter plug to the heat pads and I
now have hot pizza when I get back to the ranch. Temperature in the bag gets up to 138-140 degrees
inside. Pads come with a 10 amp fuse. Be careful when pulling the orange vinyl off of the edges as you can
also pull up the sticky side that will stick to your pizza bag. Any way I just had to share this with every one.
---here I can offer a few tips
Find and watch every YouTube video on installing seat heaters you can. You will thank me for this. Each video shows a different seat type or issue you will need to know about. They are INVALUABLE- Do not skip this!
Disconnect the battery!!!!!!!
Many seats have side airbags now, if you set one off when your head is nearby, it could kill you. This is no joke!
The main connector for the seat sensors and airbags would not come unplugged after the seat was unbolted, so I HAD to install these without removing the seat from the car- I could move the seat around, the power cable was long enough to stand it up on its front edge with the seat-back over the steering wheel to get underneath it. As it turns out I had to re-connect the battery about 20 times to operate the seat mechanism- Grrrr..This seat is 100% electric> SO, IF I had removed it from the car, I would have been stuck. You HAVE TO raise and lower the seat-back multiple times to thread the seat fabric through the gap between the seat and back rest.
If you have installed or repaired upholstery in the past, you know what hog rings are. I had never seen them before. These formed metal rings hold the plastic strips bonded to the back of the seat fabric, in the slots in the foam seats. There are skinny metal bars embedded in the seats for this. These hog rings must be removed to install the heating pads, then reinstalled carefully, in the slot in the pad and all around it. The tool they provide and the "replacement hog rings" are absolute cr@p. Throw them out when you open the package. The tie-wraps provided are junk too.
Buy or beg around 40 industrial quality 6-8" tie wraps from an engineer friend. You don't need the length but do need the width of a longer ones for long-term strength. I had some with a tiny metal catch in them- insanely strong.. Use these in place of the hog rings you remove, pull them tight and cut them off short, and they work GREAT. Use some to tie the wires too. I ran the cable under the gap under the seat track, under and through the skirt on the center console and up under the dash. Piece of cake. BUY a fuse tap for the type fuses you have, and use a meter to find a group of fuses that power off with the key or you will kill the battery if you leave the heater on. These pads use around 7 amps on hi, so it won't take long to drain a good battery with the engine off.
The upholstery work was the toughest part by far. Take pictures if you have never done this before, There are some clever (bizarre) tricks they use to clip fabric in place. You will want to remember these. I struggled with closing the back of the seat a bit because I didn't take THAT photo. The job is done, the heaters work great and the power switch is in the dash. Came out very clean, even the creases in the seats are sharp (I replaced ALL the hog rings).
I am very satisfied with the results, but it did take nearly all day to do- for an upholstery newbie. Very satisfied.
Now for the not as great: the included hog ring pliers suck, I picked up a cheap one from Harbor Freight that worked a lot better. The hog rings themselves were also junk, several didn't latch on properly and because of this I didn't have enough to fully reinstall the upholstery(I stole some from the second kit to make do). Ordered a 100 pack of higher quality rings and it made life MUCH easier on the second seat.
As others have said the included fuse taps are for the old school large size fuses, so if you have a remotely modern vehicle you'll need to splice in a mini or micro fuse tap, not a big deal but something to be aware of. The opening in the middle of the pad for reattaching the seat upholster is also not big enough by a long shot. Hard to fault them since they have to accomodate so many vehicle sizes, but you'll have to cut either the heating pad or the upholstery attachments to make it work. Switches also use a 20mm hole to install, which is kind of a rare size. A 3/4" hole saw will work but it's a tight fit.
All in all I'd definitely use these again, just have to keep in mind the negatives so you're not running to the store or frantically ordering parts to finish the job like I did!
Top international reviews
The installation process is definitely involved, finicky, and time-consuming - but I'm not holding that against these kits, because frankly that is just the nature of the beast when undertaking a car modification like this. The specifics of each install (e.g. fuse tap, running wires, button placement, seat upholstery setup) will vary greatly from car to car. This product is best suited for someone who is comfortable with some basic car maintenance work.
That said, for those willing/able to undertake the install, this is an excellent product! Would highly recommend it to anyone.
Some specifics as far as my experience installing:
- The provided fuse taps did not fit our car, and frankly also seemed a bit cheap, so I bought some fancier ones (similar to this: Pico 0956PT 10 Amp ATM Mini Blade Fuse Add-A-Circuit Fuse Holder) at an auto parts store on the day I was installing. Might be worthwhile to check this out on your vehicle ahead of time to save yourself a mid-installation run to the store.
- In general regarding fuse taps: you must make sure that you are tapping the HOT side of the existing fuse! Failing to do this would mean that the existing fuse is loaded with the current of both the original circuit and your new circuit. Although this isn't *dangerous*, per se, it could mean that you consistently overload the existing fuse, leading to you having to constantly replace it.
To test this, install your fuse tap kit, and then test your new circuit (e.g. the seat heater) without the existing fuse installed. The new circuit should work even with the existing fuse not installed. If the new circuit does not work during this test, reverse the orientation of your fuse tap (or, in the case of the kit-provided fuse tap, switch it to the other side of the original fuse).
- As some other online commenters mention, we did not bother trying to use or re-use hog rings, but used beefy zap straps instead. This achieved the exact same thing on our seats, and with much less effort.
- We found the actual insertion of the heating pads under the seat upholstery to be really tricky, so we were glad that we took the advice of fully removing the seats from the car in order to accomplish this. It was hard enough to do on a work bench, I can't imagine how challenging it would have been in the car! Installing/removing the seats took very little time on our car. Having a torque wrench and looking up the torque spec for re-installation of the seats is advisable.
• Product quality is high. No cheap parts or connectors
• Installation is as easy as your car permits. Ultimately, it was time consuming, but a very easy job
• Switches are excellent. Bright light, good click, solid feel
• Everything was well packaged, included tools and accessories, and good instructions.
• Price is very good, esp. considering retail solutions or dealership options
• The top rated review recommends a fuse-tap kit. Buy this.
The only problem I ran into is that the plugs on the heaters themselves were not making good contact. This caused the heaters to not be very warm. I cleaned them and that solved the issue.
Wired through lighter plug on passenger side, could not figure out how to re-use the OEM switch and wires.
Toggle switch works well for low and high.
Used for the past 2 winters successfully.
They look great and I'm sure they'll last a lot longer than any box store covers.
