The plan is to replace all the wire by a CAN line and a power line.


Twisting the CAN line



Preparing the power cable to be twisted arround the CAN line (I know there's a hole in my socks)



Half the job donne



Fabric tape all arround



Power part of the light ECU I'm making. there will be one on eache corner of the car to control the light, the red pcb is the conreoller connected via can that will switch on or off the light and give a feedback of the curent going into the bulb / short circuit / open circuit



PCB cooking in a reflow oven to solder the botum pad (Vbat)



Closup on the arduino nano connected to a nucleo board for programming/debugging



The power board with tha cable that connect to the light







First try
