2005 sv6 abs sensor warning & deck install

[Ponkin]

Hey Gang, seen a few threads on this but thought I would ask my specific questions. Thanks for your help in advance.

I'm having a warning light ABS for FWD 2005 SV6. My questions:

What's the cheapest easiest way to diagnose and test which sensor?
Is it possible to just change the sensor or is it built into the wheel bearing?
Where is the sensor connectors located inside the vehicle?
Would a mulitimeter detect voltage irregulars in the faulty sensor or do I need a specific GM reader to diagnose?

Also, I would like to install and aftermarket deck

Has anyone done this successfully and would you be able to point out the right connectors, open tool, din frame at a reasonable cost?

What do u think about this deck and install?
