Hi,

I am trying to install a panasonic stereo in my Caddy. I cannot figure out the power wire from the factory deck.

This is what I have so far.

Black = Ground
Yellow/Black = acc power
grey = ?
Yellow = ?

can somone help to identify which is continous power because I tried all different combination and can't get it.
