Dash control wiring?

Dash control wiring?
Hello.
I've just installed a new head unit to my car. Since I am in overseas, I couldn't get the Modifry DCI controller. So, I bought another one which functions very similar to Modifry DCI controller. (and I know few s2k people who bought the same thing and works fine except the mute button) But mine doesn't seem to work.
My questions is, this adaptor has 4 wires for Acc, Dash input(+), Dash output(GND), and GND. I've wired everything right (I assume?)
The only thing I am not sure of is the Dash output(GND) wire. I searched the web and found this can be left alone or spliced to the ground.
Does anyone know which wire is the dash output(GND) for our cars?
Funny thing about being an import car owner in Korea is that all the autoshops try to rip you off because you are driving an import (even a very easy work)
So, I decide to do everything myself. Please help.
Thanks

There are only two wires leading from the dash switch - one for mute (yellow/blue) and one for
all the rest of the functions (green/red) (from this page).
The dash switch contains an array of resisters to ground. When you press a button, the DCI is
grounded through one of the resisters, so it's not completely clear to me whether that means you
want to connect "dash input +" to supply +12v to the dash switch, or "dash output gnd" because
the wire the DCI needs to connect with is in fact a ground.
Modifry's DCI tech page may have some useful info.
BTW, don't substitute the mute wire for something else as an experiment - it supplies +12v, and
you can fry the mute circuit if it grounds.
