can anyone tell me how to get the steering column cover off to get to the ignition harness?

You actually don't need to remove the steering wheel cover to access the Passlock wires. They run down along side the ignition wires when you remove the lower portion of the driver dash area.Jeff

I am not sure how to get the lower portion off.  I took out the lower boltws but hte piece doesn't seem to want to "pop" off.
