i have the dash out of my 1974 comet and there is a black and white box under the dash. it has a part number of D4AB-14A554-A2D i took it to the local ford dealer here in town and they looked at me like i was retarded and they couldn't tell me what it was either. does anyone have any idea what it is.....
Got any pictures? It might help everyone that might be able to identify it to be able to see what you're talking about. -Scott H.
It's a part of your seatbelt interlock system. I believe it has a buzzer built in it too which often gets unplugged to get it to shut the heck up.
Yeah, I was all super careful with my box before I knew what it was. When I found out it was source of the seatbelt siren, its lifespan deteriorated rapidly.
