I am away from the car for a while, so can’t check the wires. It’s easy to pop off the puddle light and check. There are two wires to minus, most likely the other one comes from the red square light.
My suspicion is that the poor or missing grounding makes the whole system act oddly. Without grounding the relay on passenger footwell clicks, and interior lights and door open-light (on older cars) blink. With grounding all these go away.
