Hello everyone, I am new to the forum and i am currently in the midst of installing my raptor grill on my 16 edge sport. I want to wire the grill lights into the led running/fog lights on the lower facia. Does anyone know what the color codes for the three wires are. There are three wires . I am sure the one with black in it would be ground and the bright two tone is positive. but what is the third blue wire? Thanks for any help.
