Ok I pulled the radio out of the explorer because it dosen`t power on anymore. It would work ok , but once and while stop and then it would snap back on again . Now its dead, nothing , only the lamps inside the radio light. Checked fuses and all that . The radio illumination is all thats works , but still no radio sound or CD sound. Have it now on the bench to look into more . I need the actual wiring connector . The black 8 pin on the rear of the radio I think is 12 vdc DC power input . There is another smaller ( 2 rows of 4 pins connector) off to the side, maybe for the power amp .
Can anyone tell me the 12vdc constant power pin, Switched 12vdc , ground pin, the illumination lights of the radio all were workin when I pulled it out of the dash .
Just want to get it wired on the test bench to find whats the problem of why no radio and sound . Have a couple of 8 ohm spearkers to test but need where to connect the speaker and 12 vdc leads
Any help guys .

thanks
