can anyone help with a wiring problem. i am trying to install an aftermarket stereo into my 90 gtu and can't figure how to get sound. all the stock plugs were chopped off so im not 100% sure which wires go which. i tried matching up with my 86 but some of the wire's colors are different. i tried searching for it but no luck. if someone could post a picture of the stock white, blue, gound, and power/ign plugs with colors, that would help alot or just some info since i don't have another s5 to refer to.

thanks for any information
