2000 Ford Explorer Airbag Wiring

I'm installing a remote start and need to tap into the horn wire.  I want to make sure I'm not getting into any of the airbag wiring.  I need to know which wires to avoid.  Per the installation info I have and this forum the horn wire color is yellow/light-green.  I can find a small gauge wire in that color in a mix of wires that go into a yellow tube and on up the column.  I just want to make sure I'm not messing with any airbag wiring.  Nowhere on this forum or in my instructions does it provide any warnings regarding the airbag.  Any help is appreciated especially which color wires to avoid.

I went to the library and they had the wiring CD for the car.  Was able to print out a copy of the wiring schematic for 15 cents.  What a deal.  The library had the latest automotive CDs and using their computer made it a snap...
