Strange. Mine (and I'm sure most others) definitely do not have wires like that. I guess it's an oddity in going aftermarket. My aftermarket ones from ebay were shaped just like the OEM signals, but the connectors weren't a direct fit...I had to use a blade to shave down several parts just to get the plugs into turn signals.
Do those turn signals have only 2 pins in the connector? Based on the translation you got, it almost sounds like that wire is necessary for the little LED light at the bottom of power folding mirrors to work, which typically require 3 pins.
