Ford F150 - air bag light on after replacing heater core code 27

I replaced my heater core and now I have my air bag light on the code is 27 any way to reset the air bag light or find the connector that might be unpluged

27 isn't a valid LFC for a '97 F150. It uses the same as those listed in this caption:

Check out this thread, I think there is a fix for the '99
