help.. i have a problem of m perf steering wheel

[JTK_Broom]

hello.

I DIYed an M performance steering wheel with an LCD, but there is a slight problem.

There was no harness or control unit.
So I made the harness myself and ordered the control unit through eBay.

The control unit is as follows
"Genuine BMW M Performance Electric Steering Wheel V2 Control Unit 61352212797"

The problem I currently have is as follows:
Power and all settings menus are accessible.

However, information about rpm and temperature is not available.
So the temperature is displayed at -48C and the rpm is 0.

I want to solve this problem.
I really need your experience and advice.

My vehicle is a 17 year F87 Org.
