I have a separate fuse panel under the dash, and it's switched with the ignition, so I think I'll use that for power, rather than tapping into the car's fuse panel.
I am 99% certain you already discussed that fuse panel in another thread/post..... but.... mind sharing details on it just 1 more time?
-what panel was used?
-how is power routed to said panel?
-etc etc
I ran a fused wire from the battery into the passenger compartment. I taped the wire to a wooden chopstick to poke a hole in an existing grommet and pushed it through. From there, I brought the wire to the passenger's side where I connected it to the six-fuse panel. I attached it to the upper right side of the footwell with Velcro so I could remove it easily. These panels are available in various configurations and sizes. The auto parts store didn't have any, so I bought one from Amazon. That will go into my son's 2019 Fit.
I have a fuse panel on the driver's side, and that one is connected to the car's fuse panel, so it's switched. The always-live panel powers three 12v outlets I installed so I can charge a phone, etc., with the car turned off.
Take lots and lots of pictures during disassembly.
Do not remove the foam cushion. Just pull he material back.
The mounting tracks move independently.
Difficult to insert hog rings, and heaters cover the horizontal section, anyway.
Do not bunch up the excess wire under the seat. That will go to the power source.
I got my seat heaters working yesterday, and they're great. I bought the Dorman heaters for about $44 on Amazon. I used my car (2015) for practice before working on my son's 2019, and it's good I did. I learned by trial and error. The Dorman switch is less than an inch in diameter, but it was hard to find a good location for it in the side panel of the seat. That's a very crowded area. When I got the seat installed, the top of the switch was no longer flush with the panel, so I suspect some interference under the seat. When I set it to low heat, the amber light did not come on, but the heater did. Of course, with the switch installed in the side panel of the seat, you can't see the lights, anyway. I ordered a larger (1") lighted switch from Amazon, and I'll use that in the 2019 - in one of those cut-outs to the left of the steering wheel.
The seats got hot in about five minutes, and I was able to turn the pads off after about fifteen minutes. The worst of the winter is over, but these will be good for next year. When I get them installed in my son's car - hopefully, this coming week - I'll post a detailed report, with pictures.
First, installed in the panel.
Second, from the back of the panel.
Last, panel installed on seat.
I see there is only one light, but that did not light up when I switched it to the lower heat setting, although it did get warm. The heater works, but the low-temp light doesn't.
