1998 zx2 Buzzing sound From (CCM)

Was driving car at 60 mph. Radiator overheated and broke and now that i have replaced motor, radiator and then some. The constant control relay modulator (CCM) makes a buzzing sound. This box has a Z on top. This box is a rectangular box below the air intake box. I believe its a ground issue but cant find a wiring diagram to diagnostic. Any help and any advice to give i would appreciate it. Need baby on the road
