Fuse #37 is for what? The driver lumbar?
I confirm the driver seat module is only controlling the heating and the positions. Sorry, I didn't know that you was searching this info.
So, do you think it is safe to connect all the features on the same power wire?
-I don't know which fuses are used and
-I'm not sure about which connectors to use in the fuse box.
I feel it's safer and easier to just connect PIN4 to PIN9 and PIN8 to PIN13..
Thanks for your cooperation!
