Here's my 'almost famous' airbag diagnostic code chart.
The following are POSSIBLE causes for a '91.

on steady: faulty diagnostic module or poor connection at module

2 flashes: poor ground of D-sensors

3 flashes: open circuit or poor connection of power source circuit

4 flashes: faulty S-sensor

5 flashes: faulty D-sensor (D-sensor remains on)

6 flashes: faulty air bag module or poor connection of clock spring connector

7 flashes: poor ground of wiring harness

8 flashes: poor ground of D-sensor

9 flashes: open circuit between diagnostic module and D-sensor

10 flashes: faulty diagnostic module (system down, fuse burned)

Each of these codes include multiple pages of diagnosis and testing procedures. These are not guaranteed fixes.

From what ive seen, a faulty clock spring or poor connection at that poin would result in the horn being inoperative. With the horn operational, would your assumption be the module. Any ideas of what to check on the module itself?

No, you can have a bad clock spring that does not effect the horn. You need to be careful probing around with airbag components. Clock springs have a higher failure rate then modules and are less expensive. I would lean in that direction.
