Thanks for that. The diagram really helped out. Looks like they actually have one that is a possibility. I've attached the info of the one that might work. It's labelled as a "Ford truck" but could be applicable to other Ford vehicles. They just know it can be used on a Ford truck. They don't keep track of all the specific vehicles that it will work for. However, it does appear that it might work. On the diagram you attached, it appears that the upper left connection is for the ignition, the upper right is the (+). The lower left is ground and the two remaining are for the loads (one for blinkers and one for hazards). Please correct me if I'm wrong. It was difficult to read some of the stuff on there. That is the same as the flasher they have available. The only thing that I don't know is if they physically line up properly. The pic I've attached shows the physical layout of the flasher. The part number is labelled as, "EP27L"...Does this check out to be applicable to the T-Bird...SC in particular? You'd think something like that would remain constant from one vehicle type to another...but that's making things easy, and we all know Ford doesn't do that...
