Question:

i got the wire harness 4 pin for my 2010 Audi A4 and installed. Break, Running and Right turn work good. When the left turn is put on both right and left blink. Please help me figure out how to connect wires to car.

Really the only reason that both the right and left signals would blink when you activate the left turn signal is insufficient ground on the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector part # C59236. You want to make sure the ground of the wiring harness is attached to a clean bare metal surface of the Audi's frame free of paint or debris. I have attached a helpful article on 4-way wiring for your reference.
