99 Sierra Car alarm w/ remote start

  I' ve been following  for couple days this site looking for tips on how install my Royal guard two-way car alarm with remote start for my 1999 GMC Sierra 4 x 4 extended cab P/u truck  5.3 liters. I was reading and learn those kind the truck use Passlock security system OEM and need Passlock module. I bought already  DEI 555L  passlock , I have also dowloaded car wiring color and location for this truck . My concern is about the second ignition wire (white color in the ignition switch) I read have to powering . My question is where I supposed hook this wire for power up? my car alarm module don' t have extra wire or aux wire to power up this second ignition and the another question will be door lock. my wiring diagram in royal guard car alarm  module show just one wire for lock  called ( central door lock wiring ) I have to put diode in the white and lt blue wires or put a relay. please someone knows about this car alarm.  thank  you

thanks.  OhioMike1101.  I' ll  put relay to get second IGN output .
