SC-816 radio S70

I need to know the wiring of the radio wiring harness for my SC-816 radio in my '99 S70. Do you have or know where I can get this info? I am looking everywhere.

My problem is the signal for the ASC(automatic sound control) is apparently bringing lots of buzz into the radio (buzz goes away when I am stopped and I can hear it increase when I accelerate/decelerate). This occurs when listening to the AM band only, which is very susseptable to impluse noise of this sort. It is similar to alternator whine, but obviously it is tied to the speed of the vehicle thru some specific sensor. Turning off ASC has no effect. Buzz is there regardless on the AM band.

I intend to try disconnecting this speed input or at least putting a big capacitor on it or putting it thru a noise reducer type circuit normally used to clear out alternator whine.
