again........sorry for the delay, as we do not work for just answer

many of us are NOT on 24/7 & we answer as we see them
I asked specific questions above to help provide the correct answer.
You did not post if the vehicle Starts & Runs
Problem with the 1997 is it uses GM PassLock "1"
You would have to measure the Resistor value in the Ignition Cylinder, by locating the 3 ribbon wires typically thin WHITE, BLACK & YELLOW wires at the Ignition Switch.
Cut the YELLOW wire in half
Using Ohm Meter, connect RED Probe to cut YELLOW wire that goes to the Ignition Switch
Connect the BLACK Probe to ground -
Turn Key all the way to Crank position
Note the Value of the Ohm Meter
Obtain a Resistor (within 10%) from Radio Shack or Electronics Store
Tape up the cut YELLOW wire that goes to the Ignition Switch
Connect one end of the Resistor to the other Cut YELLOW wire.
Connect the other end of the Resistor to the BLACK wire of the PassLock 1 wires
Start vehicle
