Going on the assumption that you are installing a remote start....If the key has a pellet in it then you will have to bypass the VATS system for remote start(VATS is resistor based, and does not require a bypass module), if it has a factory alarm you will have to send a negative trigger to the factory alarm disarm wire for unlock and remote start. Here is the wiring information for that vehicle.

Hope this helps

So if I turn off the factory allarm with the remotestarter I don't have to do anything else to get the car to start. I don't have to install a resistor or a bypass to get the car to remote start?

The LeSabre has VATS on it and you will need a bypass module to remote start the vehicle without a key in the ignition. You can build your own or use a premade module ( I suggest the premade module ).
