PassLock?

Hey guys/girls. I just installed an Alpine cd player in my 2002 truck. Before I did this, everything worked. We cut 1 wire, the orange one, the 12v+ constant wire...decided to go get the kit, reconnected the wire and installed the cd player which works fine. Now, the truck will start, but won't remain running. The fuel is being cut and I have found out it is the theftlock feature or Passlock. We tried putting the old radio in, and it isn't theftlock, so what do I do? I have tried turning the key to the "on" position for 10 minutes, then off for 10, then tried to crank it, with no luck. I have also left it on for 20 minutes and turned it over with no luck. I have also unplugged the battery cables for 30 minutes with no luck. Any suggestions? I just want the truck to run for work Monday.
