Hey guys. I accidentally pulled 2 pins out of the yellow plug of the o2 sensor when removing my engine the other day. Its a 3 wire plug 2 black wires and one blue in a triangle arrangement of 3 pins. with 2 side by side at the top of the plug and 1 down the bottom. I pulled out the blue and one black one. I reinstalled with the black wires side by side and the blue down the bottom. Is this the correct arrangement or is the blue up top and black down the bottom?
