Yeah, it would always help to include what kind of remote starter it's from.  I hope you're asking this because you've lost the instructions, since the function of these wires is clearly detailed in there.

BLACK/ blue:  pulse before remote start----used to disarm factory alarm

BLACK/ green:  pulse after start---------if you must unlock the doors to disarm the alarm, use this wire to re-lock them after remote starting is done.

BLACK / YELLOW:  ground output while cranking------use this to activate a relay if the car has a second starter wire, like in 2001-up Chrysler vans, and most Nissans.  Also can be used to activate the "bulb check" wire if doing a GM car with Passlock 1. 

BLACK/ red:  pulse after shutdown-----if the car's doors automatically unlock when the engine is shut off, use this output to re-lock them.  Also, if working on a GM car with delayed radio power, you can tie this wire into one of the car's individual door trigger wires-----this fools the car into thinking a door has been opened, thus shutting off the radio.
