I just purchased a GT grill, factory switch and pigtails for the fogs. I've been told you have to have the JEM Module? reconfigured to think it's a GT for the relay to work and the fogs to actually work. Does anyone know anything about this? I did a search and found a thread that talked about the SJB? Again I'm on some new ground here. Any help would be appreciated. No, I don't want to add an aftermarket switch. I know that would be easier.
