thx for responding asap,,,,there are 4 wires per stereo control,left and right side,the left controls volume up and down and pushing in the button controls audio,bass treb.ect.the only wire that seems to be common, is pink/white tracer  which is supposed to be cut and grounded,of the remaining wires the are connected with with resistors,,the wiring diagram i am using is from  swix programing and is for a  2000 harley davidson,model does not seem to be specific,so it must be a diagram covering a majority of harleys,,,i can try and send you a link to swix  but if you could look it up it would probably be faster,i`m a lil computer stupid,haha,,,,,  ANY HELP YOU COULD GIVE ME WOULD BE GREAT   thx wooddogg

I searched briefly and came up with nothing.  Post a link if you can.
