why would you want to drown out the the music of your motor with noise from your radio...just kidin'. Just splice one lead in to the positive lead from the altenator and the other to the ground. Gotta say though I had the same problem added the heavy duty suppressor and still had the WHINE noise. Only after I changed my dash harness which was badly spliced into and missing connectors, replaced the 3 condensors/ suppressors, the one on the lower steering column is listed as the radio condensor did i finally have whine free music.
