So I’ve set about fitting electric adjustable seats to my coupe. It did not come pre-wired for electric seats, so we tried to piggyback 12V from the heated seats supply (since these aren’t heated, we figured we’d might as well use that).
When we connect the seats directly to a 12V bike battery, they work beautifully. When we connected the power supply from the heated seats, nothing.
We measured 11.98 volts at the seatheat connector even when contact off. Connect that to the seat: nothing. Neither on or off contact.
My question: why doesn’t this work?
Alternative: can we cable up fuses 15 and 29 normally used for electric seats, or aren’t they powered fuses by default? If not, what alternatives do we have?
Thanks!

Seat heating gets the power from the centre console heat seat buttons so you can't use that.
You need to run 12v from fuse box and then ground locally.
binwinn has done it. I beleive he also taps into the canbus from the back of the radio so the memory seats work.
He can explain it better than I can.

Thanks. Are these powered despite the car not originally coming with electric seats?

They definitely should be. Carefully push in 2 single spade connectors and then test with a multimeter.
