hi.. i had best buy install my HU last time, i replaced it with a Pioneer Deh-m6500, 1995 ford contour.

most of the wires seemed to match up, except my ford had a Blue, and orange/black that i didnt know what to connect to, and the HU had a Yellow & Black.

Problems:
the ceiling lights dont work, and a few others.
HU didnt turn on.
whenever i release the brakes, thers a peice of plastic under the shifter that clicks back and forth, only when the battery is on does it do this.

anyone know what i did wrong, do the dimmer/illumination wires have to do with this, i dont think i connected those right..?

thanks
