Help with powering S60 seat -- Not in a Car Topic is solved

There's no LIN on that board specifically. The board is purely passive switches. Seat switches behave identically to the prior board. Memory switches either pull up to 12V or (more likely) pull down to ground. Based on the diagnostic technique discussed in prior posts, can you take a stab at tracing the wires around? Take it in steps.
Trace the center terminals of each switch to the header.
Trace the top or bottom two terminals to the header.
Now you'll have the complete wiring setup for the seat switches and know which wire controls what.
Finally, trace the memory switch terminals to the header.

Final note: without the active side of the system, the seat memory buttons will be totally useless. Use them as switches to turn off/on lights instead? As abscate mentioned, reverse engineering the logic and LIN bus to get the seat memories working is a tall order - good luck.

Big thanks! I was able to get the passenger seat going with the help of this threat.

I'd also like to get the drivers side working. After poking around with the meter this is what I came up with.

pin 13/Black & pin 14/White are common but I don't see anywhere else on the board they are connected. Jbeebo, or anyone else, know how to get this working without rewiring the motors?

any update on this

I noticed the drivers side used much smaller gauge wire which runs into a control box. I abandoned the idea of using the drivers side switches and bought a used passenger switch for $30 I used that to rewire direct to the motors.

I'm new to this forum.

I have a vintage 1969 Volvo 131 that I am preparing for an enduro rally. I want to install seats from a 2008 C60 that I purchased - car was a mess but seats were good. Attached is the driver side underseat plug layout. I just need power to run the motors for the seat functions. Is there an easy way to do that by tapping into one of these plugs? Not concerned about the memory function. Thanks!

It appears that orange is side airbag (not needed), yellow is a seat slide sensor ( I assume on impact) (not needed) , green is the seat belt latch sensor (not needed). THe others I'm not sure of.

For the 2003-2004 seat model, see the following pictures.
You will only have to connect motors and battery to the freshly cut switch cable, as shown in the last image.
Mathew, thank you for this site.

Hi all, came across this while also looking to turn a seat into a computer chair. I have one from a 2012 xc60. The board is similar it seems but the contains are embedded. I was wondering if the bypass work around world of connecting the ground to terminal 2 switch 2 would still work? I'm attaching images of the board and connectors to the chair. Hope this is enough info happy to do whatever necessary to figure it out.

It appears the switches are the same.
Yes, you can do it.
R1+, R1- will go to Motor 1,
R2+, R2- will go to motor 2 and so on.
All you need is to provide 12V on 30 and 31 and make sure you have + and - in an "X" pattern for each switch.
