If you're refering to the blue/black (-) status input on the 555L then you connect it to the (-) status output of the Directed remote start system. This wire is blue or blue/black also. The BCM (Body Control Module) is under the driver side dash. It has 6 plugs in it, the purple plug is on the back. I'm going to try to copy/paste the vehicle info for your vehicle in this reply. Hope it works...

DON'T go near yellow SRS airbag looms. Don't touch them! Cutting or probing these wires may cause unintentional airbag deployment, electrical system damage or injury.
DON'T use any other testing tools besides the digital multimeter. No test lights!
Use of a test light may cause unintentional deployment of vehicle airbag, electrical system damage or injury.
DON'T crimp. Please solder all connections. Sound connections are required for proper unit functioning.
Run your wires away from all moving parts and heat sources.
Read the entire manual and watch the entire video before starting.
Run wires only through holes that have rubber grommets. Failure to comply may compromise wire insulation integrity.
Use a ring terminal for ground.
DON'T ground to a factory bolt - refer to the manual for proper grounding.

the only problem i see with that (that is if i clearly understand what your trying to say is.....) most remote start units are designed to shut down if it sees a tach signal much stonger than that orignally programed. know what i mean?

In the light blue harness, connect the grey/black for the driver's door and the BLACK/ white wire for the passenger door. You will have to diode isolate the door trigger wire from the alarm. The wires are in positions A4 and B5 and are (-).
