is the "door switch sensing input" the same as "door trigger?" It says to locate the "common wire" for all door pin switches.

Yes.

now I don't have power to my door locks. I don't know what I did because I hooked all of my alarm connections back together before I exited my vehicle. I guess I'll go back and look at the relay. I don't think its the door trigger because it'* polarity is - negative and I used the green negative wire.
