Real dash project for non ecu

Hello all
I have a non ecu car . I use Arduino nano to collect data from car and send it to rp4 . For left and right blinker iuse to read digital input for pin 1 and send it to real dash .
Can any one give me the right xml file for this

You have both left and right turn signals going to a single digital input?

The xml for this will be determined by how you have included the digital input in the arduino code

Left for pin 1 and right for pin 2

I don’t know what these pins corresponds to on your Arduino GPIO. If you send me the code you are using to build and send the CAN frame, I can send you the xml code needed to decode
