I'm putting the Eclipse AVN2210p into my 06 aveo. http://www.eclipse-web.com/avn/avn2210poverviews.html

I've got all the wiring harnesses, kits and what not. Should be a super simple job. But I don't know where to tap the speed sense cable for the GPS into the car.
Haven't opened the dash up yet, but I don't want to be fiddlding around with the wires if I don't need to.

Can someone tell me which wire i need to tap into for the speed sense function on the aveo or who I might need to contact to determine this?

Thanks so much. I'll be sure to post pictures of my rad new unit.
