I have a gaping hole on my dash with a lot of open wires sticking out of it. I figured if i got the proper wiring diagram, it would be easy to fill this hole with a new after market stereo system. problem is, seems theres alot of extra wires (some after markest, some not) that dont seem to have a proper place on the diagram.(see illastration 1.A, 1.B)

Here is what im dealing with posted_image

Wiring diagram copied from Haynes. posted_image

The red wire with the fuse holder is connected to the factory switched 12 volt wire. Needs to be connected to red wire of deck.

The orange wire going to the cigarette lighter is the constant 12 volt wire Needs to connect to the Yellow wire of your deck.

The purple aftermarket wires are a set of RCA cables . These ran to a once installed amplifier.

The 4 clear copper wires are speaker wires. They either went to a set of tweeters, or they came from the output of the once installed amplifier, to connect to the factory speaker wires.

The yellow wire coming out of your dash is either going to the fuse box, for constant power or to the once installed amplifier as the remote turn on wire.

I can't really see the black connector with the black and grey wires. Is it a 2 pin connector or was it a 4 pin with 2 wires cut off? If there were cut wires, what color were the missing wires. After further review chance are these are the factory ground (black) and the factory illumination wire (grey)

Hope this helps.
