Hello everyone. I am strugling to find any wiring diagrams about the lights. Connector on the car side has 4 smaller wires (canbus?) and 5 thicker wires. One is switched +12v and 2 grounds. Others are unknown. New lights only have three thicker pins and 2 small pins. Car is euromodel. Anyone done similar retrofit? Did not find thread about it. If there is I am sorry and will delete this one.

Answering to myself. I wired bus wires from CEM pins EN30 and EN31 to lights. But I am not getting any voltage from those pins. Bus not active/missing components inside CEM or something else is wrong. In orbit HCMR HCML are seen but not found. My CEM part number is 32217335.
