Looking to find out what all the wires in the back of my radio are. I can only seem to find the power plug Accessory,illumination,always hot and neg. I can't seem to find what the 1. Black spade plug next to it is for. 2. Then there is another plug with only brown wires I think with either 4 or 5 connectors. 3. A 2 prong connector with an metal clip on it at the bottom left and the 4. 2 speaker wire plugs. I connected a sony cdx2180 radio to the 4 power wires correctly using a chart from sony. I connected the speaker wires using only 1 pos and 1 neg for the front and 1 pos and 1 neg for the rear. The fader button seems to work which I understand shouldn't with an aftermarket system. the radio doesn't hold the memory and buttons are doing funky things. only left fron and left rear speakers work and controls on radio won't work for treb,bal,bass or fade.
Sombody please help with how I wire this sucker up.
Thanks in advance
Vinnie
