I went from a broken aftermarket receiver to a working receiver but I used my old plug with all the connections because it was easier. Right now, my problems are: I only get good reception if I push on the antennae cable, and my passenger dash amp/speaker makes static noises then cuts out completely. So I switched to the the connections and to the one I got with my new receiver and realized my old one had like three more wires. On the bottom of my receiver there is a little diagram. It reads:
-BLUE W/WHITE LINE =REMOTE (MAX. 200mA)
- RED =ACCESSORY
-WHITE= (+) FRONT SP.Lch
-WHITE W/BLACK LINE= (-)FRONT SP.Lch
then green/ green black & gray/ gray black & purple/ purple black are all speakers too
-BLACK= GROUND
-YELLOW= BATTERY

My question is: what wires in the car match these from my receiver and how can I listen to clear radio without my hand pushing on it? Thanks.

 

Probably should tell what kind of car this is for.

 

I fixed it somewhat. Now the drivers side hardly play squat. I duct taped my antennae cable so I get reception for now. Sorry about that. Its an 87 na base model. receiver is a jvc.
