Instrument panel removal and repair of odometer display, no start turnover due to PATS. How to reset same?

The odometer display disappeared. Removed panel and re-soldered the right four connectors on the message center display. Reinstalled panel, odometer display is functioning like new. With key in place a click is audible behind the dash when key is rotated to the start position, but starter is not actuated.
I understand the dash panel and the security system are interrelated and removal can or will trip the security system making it impossible to start the vehicle. What is the procedure to reset the security and possibly check for a blown fuse in the feed to the system. I believe I did remove the ground initially to prevent an Air Bag expulsion? I am assuming the feed fuse is OK at this point.
