Heated Subaru STI in a 1998 single cab Tacoma

Hey put Subaru sti seats that where heated from stock, in my first gen Tacoma.
They fit good 3 out of 4 holes line up back left needs to be lobed off and a washer needs to be welded on.
They had 4 wires for the heating elements on each seat. I just ran out both grounds and connected the hot 12v from the switch to the high power for the seat. I don’t have low but that’s fine. I used switches from an Impreza that fit basically perfect into the blanks on the driver side dash. I ran a relay from the battery with a 30 amp fuse in between, used a piggy back 15 amp fuse for the tigger wire off of the power outlets then a ground of course and a 12v wire to the switches with a 20 amp fuse before the split. If anyone wants more info like the switch pin out or what I know about the seat heaters let me know. Fun little mod feels good to have a warm backside. Will post pics of the seats and switches tomorrow !

 

What year Subaru?

Thanks

 

That’s awesome dude. Please post pics. Want to see your switch setup too.

 

Following just swapped some 4Runner seats into my Tacoma, and ma curious what the Sti seats look like.

 

I actually don’t know believe there from a 2010, a 3rd gen Impreza from 2007-2010 body style

 

Ok here are some pics of the seats and switches,I haven’t run the wires under the carpet yet.
The heated seats from a 2009-10 Subaru sti, Alcantara trim. Just Canadian STI seats came with heated stock.
The switches are from the same year/ body style but out of a 3 generation Impreza.

I had to figure the pin out for each switch
Pin 1 12v from relay
Pin 2 high power to seat
Pin 3 ground
Pin 4 low power

I had to horizontally Dremel the space for the blank on the Tacoma to get the switches to fit nicely. Each switch is slightly different where the pins connect one is wider. I dremelled off the collar around the switches to gain access to the pins. Then I made a connector for one with some Amazon stuff, I had to make another style connector out of female spade connectors for the other one. It’s a very DIY set up I’m not responsible for you lighting your truck on fire but I had very little knowledge going into this and now have heated seats so if you feeling lucky!

Also I’ll describe my relay set up I got a basic 4 pin relay 12V 40 amps
Ran wire from battery with a 30 amp fuse in between to pin 30
Ran a ground to pin 85 the trigger wire pin 86 is a wire running from a piggy back 15 amp fuse from the interior power outlets coming from the engine bay fuse box.(still have to modify fuse box at bit for it to fit, also could run from a different fuse locations but the only thing on that circuit is the power outlets so your unlikely to fry something critical. Finally pin 87 puts out hot 12v to the switches once the key is switched on. This wire is fused with a 20 amp and then splits to the two switches.

There you have it let me know if you have anymore questions I’ll do my best to answer!

 

That's badass! Do you have a picture of the back left hole to see what you've done? I might just follow suit.

 

Haha I just ran the with 3 bolts and big washers, I lobbed off the back right corner where it use to mount to the transmission hump. I figured the seat belts would hold it all together. Ideally you would weld a a bracket on too the end with a nice thick bolt hole. I knew it was going to a permanent install so that’s why I did it that way.

 

Might be able to swap the rails too or just drill out those taps and mount a new foot on it. Also love the way the head rests follow similar lines to the old bench seat.

 

Ohh gotcha, I see what you mean now. Thanks!
