-yes you can!!
-wire the remote start add-on like any other stand alone unit but it has a wire that control by an external unit like ur factory alarm w/ 2 negative pulse.
-to find this wire, 561t should say remote start input, ithink its WHITE/ blue (-).
-to obtain 2 negative pulses, use the doorlock wire. you must diode isolate them just incase someone from inside the car can start up the car accidentally w/ the rocker switch.
| ITEM | WIRE COLOR |POL| WIRE LOCATION |
| 12V|red |+ |ignition harness |
| STARTER|yellow |+ |ignition harness |
| IGNITION|pink |+ |ignition harness |
| SECOND IGNITION|lt grn (key sense)*5|- |ignition harness |
| ACCESSORY|orange |+ |ignition harness |
| SECOND ACCESSORY|brown |+ |ignition harness |
| POWER LOCK|lt. blue |+ |drivers kick panel |
| POWER UNLOCK|white |+ |drivers kick panel |
| PARKING LIGHTS +|brown | |headlight switch |
| DOOR TRIGGER|*1 |- |*1 |
|TRNK/HTCH RELEASE|gray or black |+ |behind fuse box |
| TACHOMETER|white or orange | |ignition module *2 |
| SPEED SENSE| | | |
| BRAKE WIRE|lt blue |+ |brake pedal switch |
NOTE: This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with. Use DEI part 555t or 555L. *1 Use gray/black for the drivers door and lt. GREEN/ black for the passenger door(s). The gray/black is located near the diagnostic plug harness under the drivers side of the dash, and the lt. GREEN/ black is located in a black 24 pin plug behind the fuse box in the center console. Use both wires and diode isolate each. *2 Ignition module is on the center front of the motor. Can also find tach at the PCM located behind the battery. *5 The lt. green key sense wire at the steering column must see a ground during remote start to keep the SERVICE light from coming on.
*****difficulty from 1-5, i would rate it at 4. it require diode, relay, and bypass

No you will need to program the unit to remote start upon two or three pulses. If the unit only gets one pulse it will not engage.
