93 Mustang LX 5.0 Air Bag Question

My 93 Mustang LX 5.0 air bag light blinks without pausing for about 2 minutes and goes away. I can't find a module power control unit and have read there might not be one on a 92 and 93 Mustangs.

1. First question, is there a separate power control module on a 93 Mustang LX 5.0?
2. Second question, what is possibly the problem with the light blinking non-stop until it goes away?

Thanks for your help!!!
