Which Viper model do you have, and do you have a 4 or V6, auto or manual? That would really help me determine which wires you need to tap into. Can you post the descriptions for each of these wires? Some of them are obvious (like +12V switched ignition). But other wires may not integrate into the Escape's electrical system the way they did into older cars.
For example, the door pin switch was easy when cars had all of the door switches wired in parallel, and they controlled the interior lamps directly. Now, each door switch is tied individually to the Smart Junction box, and they operate at extremely low current. The wrong connection to any wire leading to the SJB could fry it, and that's an expensive part to replace. And the door switches are closed when the door is closed, opposite of the way most door pin switches work (they close when the door opens). Most alarm or remote start instructions will have several wires that take different types of door input signals.
The tachometer line in the Escape is part of the Module Communications Network, so there's no direct tachometer line to the cluster. There are crankshaft and camshaft postion sensors, but they're tied directly to the Powertrain Control Module.
Even the starter wires are solid-state now. On 2008+ Escapes, the SJB allows you to hit START for a split second, then it takes care of sending a signal to the PCM to crank the engine until the engine starts.
Here's the starter system diagram:
I can give you anything else, but I need a little more info.
