Hello!
I'm just trying to figure out how to activate a switch to turn on heated seats, steering wheel, defroster.
I read some forums talking about pulses etc.
But I don't know if that'd work for me.
For example my rear seat switch includes the module as well. It has a connector with 5 wires. Wire 5 has power all the time. Wire 1 only gets constant 12 volts when I press the heat button.
For now I used a 5th relay output from my starter to provide power directly to pin 1. This way the heated seats start heating when the car is started with a remote.
However I basically bypassed the switch and the module.
Is there any way to wire it so that the actual button is activated, instead of providing direct current?

I have access to the wiring diagrams but they don't include diagrams of how boards are soldered
I'm not sure if I'm supposed to solder a wire from a remote starter somewhere on the board to activate the switch?

My bad, in my previous post I didn't specify I was referring to rear heated seats.
The information you provided for the front seats is correct. Here's the diagram.

Now I know that if I provide 12 volts directly to pin 1 and pin 13, it will start heating the seats. But I was wondering if it's possible to activate the switch itself, to replicate what would happen if I pushed the switch with my finger.
