You say, "...the H3's have separate door triggers for each door in the passenger kick panel..." Is this door trigger something from the Hummer factory, and normally called a door jamb switch, or is it a trigger installed for the remote start?
If it is refering to the door jamb switch; tell the master, they are not located in the passenger kick panel area on the H3.
H3 door jamb switches are located in the B-pillar for the front and C-pillar for the rear. They are the black, rubber covered switches in these pillars.
If the master is refering to some triggers installed for the remote start, disregard my previous paragraph. I do not get involved with aftermarket items that affect the BCM/PCM/SDM; other than radios. So, I will butt out.
