2005 Armada Alarm/Remote Start

im going to be doing an alarm/RS in the truck and have a few questions 1- is there any other way to get the door lock wires besidedes goin in to the drivers door? or is that because of the factory arm and disarm?? is that door panel a pain to get off? 2- the rear power lift hatch. is it just one neg pulse to open it and one neg pulse to close it so i just have to wire a neg relay up and that it??? 3-and finally is there any other imobbalizer bypass that i can use besides the one that you loose a key for i cant seem to find one? thanks anoth other info you might have for this truck would be great thanks for your help

any takers??

ok thanks the reson i said neg relay is because i cant use the neg pule alonefrom the alarm shouldnt i put a relay in wired for neg anyway just to be safe. and this is always a question i meant to ask and never did -- on new cars/trucks the dome lights have there own relays built in to the car, so if i wer to just tap into the domelight wire with the wire coming from the alarm without a relay what would happen , could that work or should i just stilll use the relays just to be safe thanks
