I noticed this key switch inside of one of our expeditions today. Small black box with the key and a green and looks like yellow led on it. We don't use it but I'd like to see if anyone has seen this before and if they know what it's for.
It looks like a general keyed switch... Most likely a cut off... I'd assume its an airbag cutoff, but all new vehicles have a sensor in the passenger's seat for the activation/deactivation of the passenger's side airbag...
Tracing the wires would be your best bet... I'd be wary of getting a key made for it and plating with it not knowing what it does...
Gonna trace em in the upcoming days. It was a admin truck first but it definitely looks up fitter added. I was curious if it was something from ford. Maybe airbags
