92 325ic aux fan prob

[hills6]

This car had been in a minor accident that damaged the plastic molded plug for the aux fan. I suspect that the fan was replaced and that the wires are a different color. The fan wires are red black & brown. The wires in the cars harness that i suspect are the ones intended for the fan are brown / Black w blue stripe / Black w green stripe. The fan works with voltage applied to the red and gnd applied to the brown. Am hoping someone could look at a schematic & tell me what the black striped wires are intended for.
