I began the process of determining the function of each wire with a multi-meter.

As I mentioned in the previous post, there are two brown wires that I assume are grounds.* One is on terminal 7 and the other is on terminal 12.

The ground on terminal 7 forms a circuit with the following wires:
2. White/blue
4. Black/blue
5. Black/yellow
8. Red/black

I'm not sure what this means yet, but I'll keep at it.

The ground on terminal 12 forms a circuit with the following wires:
3. White/black
6. White/green
9. White
10. Black/gray

I also started to test the switch function.
Terminals 2 (white/blue) and 3 (white/black) form a circuit when the seat bottom tilt for the rear of the seat is turned on.* It doesn't matter if the button is pushed up or down.
Terminals 4 (black/blue) and 5 (black/yellow) form a circuit when the seat bottom tilt for the front of the seat is turned on.**It doesn't matter if the button is pushed up or down.
Terminals 8 (Red/black) and 2 (white/blue) form a circuit when the seat back rest button is* pushed.

I assume these switches came from a car where they are mounted on the door panel? If so, there is a "middleman" in the mix. The switches connect to the door controller, which reads the signals from those individual wires, then it converts them into CAN bus signals which are sent to the seat control. The seat controller in turn operates the motors. If these came from a car with the switched mounted on the seat, then there is no CAN bus involved - they direct-wire into the seat controller.

Thanks for the reply.

The switches came from cars with seat-mounted controls. I decided that attempting to work with the canbus was beyond my skill level.

The seats came from a car with door-mounted controls. I'm planning to wire the switches directly to the motors in the seats and bypass the seat control modules. From what I can tell, the motors are connected to the 14-pin plug I described in one of my previous posts. I may be spending quite a bit of time figuring this out based on trial and error.

I found this post from about 5 years ago. https://www.benzworld.org/forums/c20...-question.html

It appears that others have attempted similar projects. I’m beginning to think this is a long term effort. I haven’t been able. To find a W204 seat wiring diagram. The W209 diagram may offer some clues, but it is an older generation and there may be significant differences.

If I am able to determine how to wire the seats, I will need to accommodate the switches in the seat trim. The first two pictures are the trim that is on the base of the passenger seat: Note that there is no provision for installing the control switch.


The third and fourth photos are seat trim from a W204 that had seat-mounted switches. Note that there is a hole that the switch fits in and a ridge of plastic around the hole that will lock the switch in place:


I had originally planned to purchase trim for a factory-like installation. However, it looks like there are differences between the two types of panels. Note the honey-comb pattern at the top of the panel from the C63 seats. There is a seat component that fits in that honey-combed area.

I will need to develop a template and then carefully cut a hole in the C63 trim. I'm not sure how I will fasten the switch in place. I may have to use duct tape or packing tape.

JB Weld is the new duct tape.

Thanks for the suggestion. JB Weld will make a srtrong bond, but I need to be sure I can remove the switch if I need to replace it. Iím working with used parts and they have an unknown pedigree.

I really meant that more of a joke. Although, you could use JB Weld to built up some mounting posts and secure some nuts on the inside of the panel, then fashion a bracket and bolt it to the back, if that makes any sense. Duct tape would probably come loose in the heat.

The mooring posts might work. I may be able to use JB Wild as long as I don’t use too much and position in it so that I can cut it off if necessary.

One trick I learned with sing JB Weld to fashion "parts" is to use duct tape. Not the fabric "duck tape", but real metal duct tape. It can be molded into a shape ou need, filled with JB Weld, then peeled off when done.
