Rostra
Rostra Vehicle Application Search Results I'm looking at 250-1871, thumbwheel adjustment

Heatedseats
Seat Heater for Cars and Trucks from HeatedSeatKits.com
They have a thumbwheel also

No doubt, many seat heaters can be found on Ebay, Amazon etc. But, what I really need to know is whether or not the thumbwheel fits into the switch blanks that already exist in the vehicles that aren't equipped with factory bun warmers.

I bought this kit of ebay and installed them last November. The switches fit into the blanks in the center console (next to DAC) with just slight modification. Seats get hot within 2 min and the switches have an orange/amber led light on them to indicate they're on.

Here is the pic of the switches installed. Also, this write up was very helpful during the install.

Holy cow, those switches fit perfectly. I wonder if all vendors use the same size switches for their bun warmers!
 
From my understanding, Rostra are the OEM for Toyota seat heaters. I heard this after I had installed the Rostra units on my 4R.

3D Printed Rostra Round Switch Plates

My bro also created custom printed switch plates for the round switches.

I was initially worried about the heat coming up through the foam on the Clazzio seat covers, but they get toasty warm pretty quickly.

alia176 - I'm in the process of installing the Rostra heaters (p/n 250-1872) with the dual 5-position dial this week. I'll post pictures of the switch installed in the center console when I'm done.

Does anyone know the best place to tap into for the switch illumination (I assume)?

Darren, I heard the same thing as well. Seems that nobody has the dial switch installed in their Runner.

The most likely reason no one has the dial switches is because they (Rostra) won't fit in the stock 3 middle holes in the console. 4Rs with the factory heaters have two holes on either side of the middle switch holes.

Cool, I just ordered the same set too. Once I take the seat out, I'll be replacing both foams, new seat heater and a new inflatable lumber from Rostra as well.

Very good point!
 
I took some pictures of modifications I had to make to the hole in the console to fit the Rostra Dual Dial Switch. Basically, I had to square off the corners and cutoff the lower part of the hole where it gets smaller. The the switch fits nice and snug now.

Excellent work!!
 
I would prefer to have independent switches for left and right seats. I see on Rostra's website that they do not offer that option. Does that mean I have to buy two single seat kits? Anyone know?

Have you guys seen the reviews on Amazon of the Rostra kit? It is not so great. Folks are complaining of the switches being lower quality, bleed through in the lighting etc.

I am curious how the cheaper eBay kits are holding up. If they are all cheap/non-OEM standard, maybe better to go with the cheaper kit instead of Rostra?

So far I have had no issues with the ebay kit I bought last fall. The switches work well and seem to be solid. I haven't noticed any bleeding through but I have SE with black/dark gray cloth seats.

Way old thread, but thought I post up a variation of the install using the same switches but in the factory positions:
