How's the water!? I'm in S'toon.
I put a Compustar Pro remote start/alarm system in my Rav last winter. I got most of my wiring info from here:
99% of where you will need to tap into is right under the driver's steering wheel. There is one bundle where you will tap the majority of your wires into and everything else is in close proximity.
Some info I used (I checked every wire with a voltmeter to ensure it was correct):
