The point that the Theft Deterrent Module had the security light flashing meant it'* not reading the correct resistance range through the key lock cylinder and the chip on the key. Most likely that'* due to the 7-10 very fine wires within each of the little white wires having lost a few of the hair thin wires to breakage when the tilt column is flexed up and down. That changes the resistance of the little wires between the TDM and the key lock cylinder.
When the security light stays on steady, that indicates the TDM is in one of the 4 (IIRC) failure modes. One of those is that that module decides it is not working correctly and just turns the light on steady and allows the car to be cranked. My 98 was in that mode for 3-4 years. Then one morning it refused to crank at the local quick market when I picked up coffee. The starter apparently had started acting up and may have spiked the system causing the TDM to wake up.
I ended up cutting the two fine wires inside the orange sheath fairly close to the steering column, leaving me a lot of wire to attach a resistor series that I built from Radio Shack resistors. I soldered it in and slide the heat shrink tubing I had put on over the exposed resistors' leads.
If you are not able to locate the orange sheath wire and do this yourself, I suggest finding a shop that installs car alarms and pay them to insert the correct resistor--it'* my understanding this is what they do to bypass the system to install their aftermarket alarm system.
