ColorMFA

Hi I have colormfa on 8N TT and updated software to latest version but still cannot get reverse to show. How can I make this work step by step help if possible?

For 8N the reverse signal must be connected to the TrInput 15 on ColorMFA PCB.
You can take this signal from the reversing sensor or from the reversing lamp. You can connect directly to the ColorMFA PCB or use the free pins of the dashboard connector (The gray connector should have free contacts).

Thank you
