1999 Dodge Ram Python 574 / Viper 5704 Help

I’m new to alarms installs but not to wiring, soldering, using a DMM. I intend to verify all my connection prior to soldering. I hate using black tape. Is there an alternative without cutting the connection wire?

According to a few sources, my truck has the following configuration:

Constant 12V+   Pink/Black or Red   Ignition Switch Harness

Starter     Yellow or Blue / YELLOW          Ignition Switch Harness, Must Add Relay for Remote Start

Ignition   Dark Blue      Ignition Switch Harness

Ignition 2 BLACK/ White     Ignition Switch Harness

Accessory         BLACK/ Orange   Ignition Switch Harness (Heat/AC)

Tach     BLACK/ Gray        PCM Passenger's Rear of Engine on Firewall

Neutral Safety Wire     BLACK/ White      (-) Ignition Switch Harness

Brake Switch    WHITE/ Tan         Brake Switch or Ignition Switch Harness

Trunk Pin n/a

Parking Lights    BLACK / YELLOW (+) Driver's Kick Panel White Connector Driver's Kick Panel

Head Lamp        Light GREEN/ Black    Steering Column

Factory Disarm Light         GREEN/ Orange    ( -) 24 Pin Connector behind Driver's Dash

Door Trigger          Yellow        (-) Driver's Kick Panel White Connector Driver's Kick

Door Lock          ORANGE / Purple         (REV) 10 Pin Connector Driver's Kick Panel Reverse Polarity

Door Unlock       Pink/Purple Driver's Kick Panel

Driver's Lock         ORANGE / Black          Left Kick Panel

Windows Up LF=Light Blue, RF=BROWN / White

Windows Down LF=White, RF=PURPLE / White

I have a glass break sensor to add. I’m considering a remote window control sensor as well.

My questions: Can someone please verify my wiring? I’m not sure I’m interpreting the installation manual correctly. DEI is very confusing.  Where do I need to add relays? Do I need to add any diodes anywhere? It appears that this unit has onboard relays. Can I use any of them? Do I need an other relay for remote start?

Thanks for all your help.
