Need help locating a couple wires

Hey guys,

New to the N body world here, I'm installing a pioneer nav unit in my wifes alero and I need some help finding the VSS (Vehicle Speed Sensor) Wire and the location of the ebrake wires, I figure thier under the bach of the console but is there a way to get at them without taking out the console ?

Thanks a bunch for helping a N body newbie
