The best thing you can do is get a data bus module for these. All you will have to do is hook up 1 wire at the data link connector and it will do all your door lock/alarm functions. Otherwise you have to go into the doors.

Is this also true for a 2000 Silverado? If so, what part #? Thanks.

No, 2000 you don't need this module. You can get all the lock, unlock, disarm wires at the module under the steering column.

It can be done w/o the data-bus module, but you have to put relays inside each door. It sucks bad. Data bus is definately the way to go.
