Yes, just add a wire that does the same as the switch.
You could use a small relay to bypass the button entirely or measure the voltage across the button pins when on/off and duplicate that with an output(power or ground, maybe a resistor needed) that you have available.

Thanks for the advice. Might be an overkill for my abilities and need though, but I'm sure it can help someone in the future.

I think I'm happy with providing 12 volts to pin 1 on the switch while the car is remote started. Once I get inside the car and start driving, the remote obviously disconnects/cuts out power output and the rear heated seats can be regulated with the button by the passengers.

Next on to the heated steering wheel.
Trying to figure out the diagrams.



Connector X01033 is the one I need I believe.
Now it seems pin 1 & 2 are connected to a heating element. So I guess there are 2 heating elements inside the steering wheel.
Pin 3 goes to a symbol that I don't know.
Pin 4 is obviously ground

I guess I need to provide 12 volts 10 amps to pin 1&2 to activate heated steering wheel.
Not sure about pin 3.
Will experiment and report back.

Pin 3 is a temp sensor /overheat switch.

Does it turn off heat to the steering wheel at a certain temperature? How does it do it? It doesn't seem to cut off power to the heating elements.

I found a decent video describing the insides of the steering wheel with emphasis on the heating element

Just tried connecting a 12 volt 1 amp adapter to I01033 connector. The steering wheel started warming up slowly. It definitely works.

It's kinda clear now. Red and brown wires get the juice from clockspring and pass it over to the connection with two blacks, one brown and one black and white wires. They connect directly into the filament that runs through the steering wheel.
The connector with green, yellow and blue wires connects to the steering wheel heating switch.
When the heating button is pressed, Steering wheel heating control unit probably allows voltage to go from red and brown wires to the 4 wire connector.

Because the button is separate from the controller this would be a good time to activate the controller instead of by-passing it. Because the controller is in the steering wheel though you have a problem with getting any extra connections to it unless there are some unused tracks in the clock spring.

Figured out the rear defrost.



To activate the rear defrost, you can activate the defrost relay by providing negative to pin 7 on the picture.
So I simply spliced "ground when running" into pin 7 from my remote starter to activate the rear defrost.

Now the only problem is the steering wheel.

The problem with the steering wheel is that I can't even run wires inside as I wanted, because of course it rotates lol.
Any ideas how to do it through the clockspring?

After much pain I think I figured it out.



#1 is the connector that connects to the heating element of the steering wheel
#2, red and brown wires, provide power to #1
#3 provide power to #2
#4 is the connector that goes into #3

#4 connector consists of 2 wires. Brown and green/black. It provides power. However I'm not sure why power wires is green and black and not red.

Now I spliced into the green wire with 12 volts on remote start of the car. If my theory is correct, it should work.

But I'm thinking I must've overlooked something.
