I just keep having issues with this install.... The latest problem I've run into is the fog lights. I've got a new roush stage 3 fascia in place, and I installed the proper wiring harness and everything. The lights worked fine after I tested them. The next day I wanted to protect the connections (The kit I had didn't have replacement hardshells on the harnesses, so the wires just plugged in, partially exposed from the back) so I wrapped them up tight in electrical tape (Not a good call, I guess?) The next time I pulled the switch (No engine running); I could smell something burning, and some smoke rising up from the passenger side of the hood. Quickly I killed the switch and disconnected everything. After that, I looked around closely to see what had produced the smoke/burn. The tape seemed to be ok, the connections weren't burned, and the bulbs were still perfect. I couldn't figure it out. So I checked my relay and fuse. The fuse was fine, but the relay had a little bit of burn discoloration on two of the prongs. I replaced it with the correct relay, thinking that had been the problem, and tried again. No light. Lastly, I put a test light to it, and it seems I've got no power going to the fogs. What else could it be? Stock GT fogs are 899 bulbs, and the new bulbs are 9005s. That’s not a huge deal is it? Even if it was, I’d be able to get power back by replacing the relay, right? I'm out of ideas. Is there a phantom part I'm not aware of? Any guesses would surely help me out a bunch. Thanks in advance. -Ron

I've been going through the owners manual looking at the fuse listings, and I see one for the foglight relay in position #5, and a fuse 27 listed in there as well. Are these the only two that could be causing my loss of power? They're both in the engine primary fuse bay.... Are there any other fuses/relays to check other than those two? Someone at least needs to chime in and tell me I've checked the only two possibilities.... I despise paying people to look at my car in a shop of any kind. It's the principle of the thing, I guess. Don't make me do it, please!

Do you have voltage at the relay? If so, check the connection to the fog light output side of the relay. If none is there, unplug the fog lights from the relay, and recheck the relay side. If no voltage, the relay is bad, if there is voltage, there is a short somewhere in the fog light harness.

check your power at output side of the realy if you got power there, move on to the fuse if you have power there, then check your fog lights you might have a short somewhere
