I understand the fogs will not mount to the bumper without the tabs but people have posted about fiber glassing or modifying the bumper but they did not say how they did it. I found the Pontiac G6 bumper even without the fogs has the tabs. I am not sure how cutting that part out of the G6and fitting it in the LT bumper would work. Could not find a damaged bumper I could get cheap. I may just try to make brackets to attach to the bolt and metal near by where the fog lamp would be.
I hooked up a lighted fog switch from a G6, the led did not light but I could hear the relay click. I thought if I used a lighted switch I would not need to pay get it programmed to get the light in the dash. I do not have the fog wiring off the headlights but I read a post that they just wired the lights to the fog fuse to bypass the programming.(they used factory fog switch, wiring and relay.)
