I was wondering if someone can give me the wiring for a mark lt 2007. Is it one wire that connects to the steering wheel from the device of pac. OR is it each controll, One wire for increase in volume another for decrease another for forward of the cd or is it one wire that does this as it shows in the instruction. the deck will be a d3 any help would be apreciative thanks

your going to run into a problem using it with a d3, because the d3 doesn't come with a remote and in orger to program the pac you need the factory remote, pretty much the pac is just a universal remote, and in order for it to know what signal to send to the deck you need to program it.

as for the wire color the pac normally comes with a giant sheet that unfolds and has every car it works with and tells you the color of the wire, off hand i don't know the color on a mark lt.
