I upgraded to the GT Bumper cover and grill with fog lights. I read in a very old post that the fog light Icon and the word pull on the light switch can be illuminated. I remember that the post indicated that you had to run a jumper wire. I can't figure/remember what color wires had to be jumped, adn where these wires are to be jumped? On the switch? In the power distribution box under the hood?
