Pre-Wired For Heated Seats

In case anyone was wondering some 2nd gen Tacos in the States are completely pre-wired wired for heated seats.

First I checked for the relay:


Then checked for the switch wiring (there is a dedicated R & L switch) the plugs are different for some reason:

Im willing to bet these capped wire ends under the seat are for the elements:

Just get the heating elements, connectors, switches, and relay and everything is nearly plug & play.

For trim reference, I've got a 2012 TRD Sport.

 

Watching this with interest...going to have to check my 2010...

 

Very nice.

I'm wagering my little 5 lug won't have that. Although it was prewired for back up camera in tailgate and at mirror, yet not for fog lights.

But I just park in the sun to heat my seat

 

Well isn't that neat. Wish I lived somewhere cold

 

Usually what I eat has a strong influence on the temperature of my seat. However my wife is strongly in favor them being electrically heated

 

They're different so the worker at the factory doesn't have to wonder which one is for driver and which is for passenger on the assembly line.

 

@LivinLoud you could be a lucky duck!

 

Subd, adding in the near future.

 

Natural gas is where it's at.

 

I put them under my Clazzio's and put the Seat Heater Button in the shift console. Love the bun warmers in the cold weather

 

I hate being the bearer of bad news but if you are referencing those White Wires with the Black Stripe. Those are standard for Toyota Ground connection. I would almost be willing to bet they are all tied together on the end.

 

No you don’t

 

That's kind of what I thought at first. But why would there be 4 ground wires under each seat all open at the end? They're bound together and capped off with piece of rubber tubing filled with some sort of hard drying cement.

I have a wiring diagram somewhere. I just need to find it.

I guess I could just get a relay, plug in a switch and see if they have power.

 

Very curious..need to know now

 

You may get lucky, but I'm not buying into Toyota using white wire with black stripe for all grounds in the truck. then flipping that on its head for the seat heaters... I think those wires are tied to ground. If you have a meter a free method to check would be to read the resistance of each wire to the chassis. I'd think they would read near 0 Ohms. IN which case they would all be ground wires.

 

I did find this...






Those do appear to be ground wires. I should have some time tomorrow to pull the seat at look for the blue an purple wires.

 

I agree. If the connectors are there they would be three wires for each seat.

1. Lavender.
2. Violet.
3. White with Black Stripe.

 

those are 100% ground wires in that picture. trust me ive been throught the entire harness on a tacoma they have alot of grounds tied together like this.

 

Subbed! This would be cool if it actually works!!
