I'll need to check if they turn on and off.

So the lumbar and the bolsters switches are not evaluated by the seat module. The valve body evaluates those so, I need to actually check for power.

Pins 4/8 did exist on the original passenger connector.

Still confused why position sensor is not registering.

All this is.going to be something simple that I missed.

I haven't really done any debugging this week. Work has been hectic.

Edit:
The heater is working. No issues with either seat heater.
Lights are not working on either seat bottom,
The lights did work on the old seats. Something else to look at.

X12*1B (1) is not populated on the old seat. Distinctly missing.
Question is on the car side of the connector is that wired? If not I'll need another wire from driver's side to passenger side pin 1 to get it all functional.
