Clarification on wire voltage

I am doing some preliminary wire probing in prep for the installation.  My vehicle is a 2003 Dodge Ram without the factory alarm.  Please help answer these questions:  1.  I was probing for the accessory wires (ignition harness)and located the BLACK/ wht that reads 12 volts in the accessory position and in the run position and goes to 0 when starting(and without the key -not constant).  The second accessory wire was orange and shows 0 volts in accessory position and 12 in run and goes to 0 during start (and without key).  Is this correct for the 2nd accessorry wire?  I could not find another wire in the ignition bunch that acted like the BLACK/ wht wire.   Number 2 question:  I was probing the dook lock wire which is a single WHITE/ green wire.  Without moving the switch it reads about 4.8 volts.  When the door lock switch is moved, the voltage drops about 1 volt or so to about 3.2 volts.  Is this correct?  My install guide says this wire should read 12 volts at no movement not 4.8.  Question number 3:  Is it acceptable to use the yellow/blue (+) wire in the driver's side A pillar as an all door trigger instead of using the 4 independent door triggers and isolating them all with diodes?   Thanks in advance.  I ordered a crimestopper 2016FM alarm and will install it next week.

OR U could try this........................

*LT GRN/ORANGE-Arm/Disarm Must See A Ground Pulse thru a 1.5K Ohm Resistor To Arm/Lock and a Ground Thru A 550 Ohm Resistor To Disarm/Unlock Use Double Pulse Unlock. (Installer has Reported 249 Ohm Resistor For Disarm) 

* Also Has Been Noted As RED. **Ignition # 4 : ORANGE Ignition Switch Harness Air Bag Control Module. *** 64 Pin Connector Located On Firewall By Driver Fender VLT/BLK pin # B7

Ok, so to hook up the remote start 6-pin high current connector it would go like this:

Pin 1: Starter output to the yellow wire

Pin 2: Accessory (Heat/AC) to the Dark Green (Blower) wire

Pin 3 and Pin 4: +12 volt to the pink/black and RED / wht wires

Pin 5: Ignition 1 to the Blue 16 guage wire

Pin 6: Ignition or Accessory #2 output to the RED / white ignition #2 wire and hook up the accessory BLACK/ white wire together with pin 2 using a relay?

Does this look right?  Also, any answers on questions 2 and 3 from original post?  Thanks again,
