Need help with Pibus and RPi3B+

have no idea what's the problem with the mirrors.

Got new relay. With new relay screen turns black. But voltage pin doesn't give any voltage to rear view camera.
But don't want to play with it anymore, so connected voltage from reversing light. Everything works, so will leave it at that.

And old relay might be good, one pin was unsoldered for some unknown reasons.
