Hi everyone! I’ve been looking around and asking about the seat wiring for my 2008 e60 seats!
my project is to have it on my simulator with a power supply to power them!
I tried to power them with a booster pack and nothing moved .. if anyone can guide me true the wires it would help allot since i can’t find any wiring diagram... here is my wiring







i just bought a 12volt power supply with 15amp output and a pulse generator for the Can Bus

Does this give you what you need?

Hmmmm, looks smaller than it did where I was editing the photo.

Fortunately I think all you need is in the top left corner anyway.

i found that diagram too but i can't read it... one told me that my brown was negativ and orange positiv and Bus was the yellow and black! can't figure out how to power it on... so surely im missing something or wtv it is the seat is not moving..

Weird. I would imagine the seats would move with just power supplied.
So to verify, you:

• Provided power at pins 23 and 3
• Ground at pins 2 and 11

When I read the diagram that is how I interpret it.

pin 23 and 3 how much vlotage do i give them? and those are on the yellow connector?

i just want to do it right the first time since i don't have a second seat if i fry this one I'm screwed! just to recap the thing i will try if thats what you suggest! plug the big red wire with pin 23 and 3 on 12volt positive lead and the big brown wire with pin 2 and 11 on the ground lead, corect me if im wrong il wait for a response before connecting anything! and if you are wondering i do have the connector to simplify the jump on the pins

maxseguin

so i traced back the wires and found where they go!

so pin 2-3-23 goes to the controller on the seat but those are the only wires on the controller

The controller under the seat has all its on controls going to the seat parts so there aren't all that many wires (if I remember correctly) going into that yellow connector. You've got some for occupancy sensor on the passenger seat, can bus for the heated seat controls, seat belt switch, and then power for the controller. I would think if you got power to the controller that is all you'd need. You could even bypass the yellow connector and give 12 volts directly to the controller. I can't verify at the moment but perhaps this even I can go out and unplug my yellow connector and see which pins are ground and which have voltage.

maxseguin

are you sure? on my end my Controller on the side of the seat has 3 wires (those 3 goes to the yellow connector) none goes to the computer under the seat just directly into the yellow connector so if i apply power how is it going to communicate? and my seat is a driver side so i don't think it has a occupancy pad
